   Third side length = Perimeter - (Length of side 1 + Length of side 2)
                     = 934m - (828m + 10m)
                     = 934m - 838m
                     = 96m

Therefore, the length of the third side is 96m.

Problem: An equilateral triangle has a perimeter of 114cm. What is the length of each of its sides?

Claude-3 Opus:

Let's solve this step by step:

1) In an equilateral triangle, all sides have the same length. Let's call this length $x$.

2) The perimeter of a triangle is the sum of the lengths of all its sides. In this case, the perimeter is 114cm. Therefore:

   $x + x + x = 114$
   
   $3x = 114$

3) To find the length of each side, we divide both sides of the equation by 3:

   $3x/3 = 114/3$
   
   $x = 38$

Therefore, the length of each side of the equilateral triangle is 38cm.

### Answer: 38cm

Expected answer: 38

Correct? Yes

Problem: An equilateral triangle has a perimeter of 69m. What is the length of each of its sides?

Claude-3 Opus:

Let's solve this step by step:

1) In an equilateral triangle, all sides have the same length. Let's call the length of each side $x$.

2) The perimeter of a triangle is the sum of the lengths of all its sides. In this case, the perimeter is 69m. Therefore:

   $x + x + x = 69$
   
   $3x = 69$

3) To find the length of each side, divide both sides of the equation by 3:

   $x = 69 \div 3$
   
   $x = 23$

Therefore, the length of each side of the equilateral triangle is 23m.

### Answer: 23m

Expected answer: 23

Correct? Yes

Problem: A triangle has sides of lengths 464m and 377m respectively. If the total perimeter of the triangle is 907m, what is the length of the third side?

Claude-3 Opus:

Let's solve this step by step:

1. We know that the perimeter of a triangle is the sum of the lengths of all its sides. Let's call the unknown third side $x$.

2. Given:
   - Side 1 = 464m
   - Side 2 = 377m
   - Perimeter = 907m

3. We can set up an equation:
   - Perimeter = Side 1 + Side 2 + Side 3
   - 907 = 464 + 377 + $x$

4. Simplify the right side of the equation:
   - 907 = 841 + $x$

5. Subtract 841 from both sides:
   - 907 - 841 = 841 - 841 + $x$
   - 66 = $x$

Therefore, the length of the third side is 66m.

### Answer: 66m

Expected answer: 66

Correct? Yes

Problem: An equilateral triangle has a perimeter of 966m. What is the length of each of its sides?

Claude-3 Opus:

Let's solve this step by step:

1) In an equilateral triangle, all sides have the same length. Let's call this length $x$.

2) The perimeter of a triangle is the sum of the lengths of all its sides. In this case, the perimeter is 966m.

3) Since all sides are equal, we can express the perimeter as:

   $3x = 966$

4) To find the length of each side, we divide both sides of the equation by 3:

   $x = 966 \div 3 = 322$

Therefore, the length of each side of the equilateral triangle is 322m.

### Answer: 322m

Expected answer: 322

Correct? Yes
