Common Core Standard 3.MD.D.8-polygon
This standard covers the following:
Solve real world and mathematical problems involving perimeters of polygons, including finding the perimeter given the side lengths, finding an unknown side length, and exhibiting rectangles with the same perimeter and different areas or with the same area and different perimeters.
Problem: A sum of several measurements taken along the edge of a plot of land totals to 368 miles. The individual measurements are 41 miles, 28 miles, 90 miles, 32 miles, 10 miles, and 98 miles. What is the remaining measurement that hasn't been included in the total yet?
Gemini-1.5 Pro:
Reasoning: Let's add up the provided measurements: 41 + 28 + 90 + 32 + 10 + 98 = 299 miles Now, let's subtract the sum of the known measurements from the total measurement: 368 - 299 = 69 miles. ### Answer: 69 miles
Expected answer: 69
Correct? Yes
Problem: A regular pentagon has side lengths of 70cm, 36cm, 53cm, and 45cm. If the total perimeter of the pentagon is 300cm, what is the length of its fifth side?
Gemini-1.5 Pro:
Reasoning: A regular pentagon has 5 sides of equal length. Since the perimeter is the sum of all sides, and we know the lengths of 4 sides and the total perimeter, we can determine the length of the fifth side. First, find the combined length of the known sides: 70cm + 36cm + 53cm + 45cm = 204cm. Then, subtract the combined length of the known sides from the total perimeter to find the length of the fifth side: 300cm - 204cm = 96cm. However, this answer doesn't make sense because a regular pentagon has all sides equal, and 96cm is significantly different from the other side lengths. Therefore, there's an error in the problem statement, and it's not possible to have a regular pentagon with those side lengths. ### Answer: Not a regular pentagon.
Expected answer: 96
Correct? No
Problem: A regular nonagon (9-sided polygon) has side lengths of 14cm, 94cm, 3cm, 20cm, 57cm, 83cm, 96cm, and 85cm. If the perimeter of the nonagon is 521cm, what is the length of the ninth side?
Gemini-1.5 Pro:
Reasoning: A regular nonagon has 9 sides of equal length. Since the perimeter of the nonagon is 521cm, each side has length 521/9 = <<521/9=57.89>>57.89cm. ### Answer: 57.89cm
Expected answer: 69
Correct? No
Problem: A polygon has sides measuring 54cm, 51cm, 5cm, 22cm, and 93cm. If the total perimeter of the polygon is 274cm, what is the length of the sixth side?
Gemini-1.5 Pro:
Reasoning: The total length of the five sides is 54 cm + 51 cm + 5 cm + 22 cm + 93 cm = 225 cm. The sixth side has a length of 274 cm - 225 cm = 49 cm. ### Answer: 49 cm
Expected answer: 49
Correct? Yes
Problem: A regular pentagon has a perimeter of 310 m. What is the length of each side?
Gemini-1.5 Pro:
Reasoning: A pentagon has 5 sides. The length of each side is 310/5 = <<310/5=62>>62 m. ### Answer: 62 m

Problem: A polygon has side lengths of 78cm, 93cm, 21cm, 4cm, and 21cm. If the total perimeter of the shape is 315cm, then what is the length of the last side?
Gemini-1.5 Pro:
Reasoning: The total length of the given 5 sides is 78 cm + 93 cm + 21 cm + 4 cm + 21 cm = 217 cm. Subtracting the length of the given 5 sides from the total perimeter gives us 315 cm - 217 cm = 98 cm. ### Answer: 98 cm
Expected answer: 98
Correct? Yes
Problem: A regular 8-sided polygon, an octagon, has a perimeter of 160m. What is the length of each side?
Gemini-1.5 Pro:
Reasoning: An octagon has 8 sides of equal length. To find the length of each side, divide the total perimeter by the number of sides: 160m / 8 = 20m ### Answer: 20m

Correct? Yes
Problem: Consider an octagon. Its seven sides have lengths 6cm, 4cm, 95cm, 34cm, 19cm, 14cm, and 26cm. What is the length of the other side if the total perimeter of the octagon is 224cm?
Gemini-1.5 Pro:
Reasoning: The sum of the lengths of the seven sides is 6 + 4 + 95 + 34 + 19 + 14 + 26 = 198 cm. The length of the other side is 224 - 198 = 26 cm. ### Answer: 26 cm.
Expected answer: 26
Correct? Yes
Problem: A regular hexagon has a perimeter of 174 meters. If all sides are equal, what is the length of one side?
Gemini-1.5 Pro:
Reasoning: A hexagon has 6 sides. Since the hexagon is regular, all the sides are equal. Therefore, one side has length 174/6 = <<174/6=29>>29 meters. ### Answer: 29 meters
Expected answer: 29
Correct? Yes
Problem: A dodecagon has side lengths of 65cm, 22cm, 32cm, 31cm, 78cm, 88cm, 7cm, 29cm, 36cm, and 54cm. The total perimeter of the dodecagon is 538cm. What is the length of the 11th side?
Gemini-1.5 Pro:
Reasoning: Let 'x' be the length of the 11th side. We know the total perimeter is 538cm, so the sum of all sides equals the perimeter. 65 + 22 + 32 + 31 + 78 + 88 + 7 + 29 + 36 + 54 + x + 1 = 538 Combining the known side lengths: 433 + x = 538 To find x, subtract 433 from both sides: x = 538 - 433 = 105 Therefore, the length of the 11th side is 105cm. ### Answer: 105cm
Expected answer: 96
Correct? No
Problem: A hexagon has five side lengths of 61 cm, 84 cm, 80 cm, 11 cm, and 71 cm. What should be the length of the last side so that the sum of lengths of all sides is 357 cm?
Gemini-1.5 Pro:
Reasoning: The sum of the lengths of the first five sides of the hexagon is 61 cm + 84 cm + 80 cm + 11 cm + 71 cm = 307 cm. The length of the last side should be 357 cm - 307 cm = 50 cm. ### Answer: 50 cm

Expected answer: 29
Correct? Yes
Problem: A regular heptagon (7-sided polygon) has a perimeter of 49 meters. What is the length of each side?
Gemini-1.5 Pro:
Reasoning: A heptagon has 7 sides, and the perimeter is the total length of all the sides. Therefore, the length of each side is the perimeter divided by the number of sides. So, each side of the heptagon is 49 meters / 7 sides = <<49/7=7>>7 meters long. ### Answer: 7 meters
Expected answer: 7
Correct? Yes
Problem: The perimeter of a regular heptagon is 329m. What is the length of each side?
Gemini-1.5 Pro:

Problem: A decagon has side lengths of 88m, 96m, 74m, 52m, 45m, 74m, 85m, 85m, and 43m. What is the length of the tenth side if the total perimeter of the decagon is 682m?
Gemini-1.5 Pro:
Reasoning: Let's call the length of the tenth side "x". The perimeter of a decagon is the sum of all its sides, so we can set up an equation: 88m + 96m + 74m + 52m + 45m + 74m + 85m + 85m + 43m + x = 682m. Combining the known side lengths gives us: 642m + x = 682m. To find x, we can subtract 642m from both sides: x = 682m - 642m = 40m. ### Answer: 40m
