Problem: A rectangle has a length of 21m and a width of 37m. What is the perimeter of the rectangle?

Claude-3 Sonnet:

To find the perimeter of a rectangle, we need to add the lengths of all four sides.

Given information:
- Length of the rectangle = 21 meters
- Width of the rectangle = 37 meters

The formula for the perimeter of a rectangle is:
Perimeter = 2 × (length + width)

Substituting the given values, we get:
Perimeter = 2 × (21 meters + 37 meters)
Perimeter = 2 × 58 meters
Perimeter = 116 meters

Therefore, the perimeter of the rectangle with a length of 21 meters and a width of 37 meters is 116 meters.

### Answer: 116

🔗 Problem

Problem: A rectangular garden has a length of 50 feet and a width of 20 feet. What is the perimeter of the garden?

Claude-3 Sonnet:

To find the perimeter of a rectangle, we need to add the lengths of all four sides.

Given information:
- Length of the rectangle (garden) = 50 feet
- Width of the rectangle (garden) = 20 feet

Step 1: Find the sum of the lengths of the opposite sides.
Length of the opposite sides = 50 feet + 50 feet = 100 feet

Step 2: Find the sum of the lengths of the other opposite sides.
Length of the other opposite sides = 20 feet + 20 feet = 40 feet

Step 3: Find the perimeter by adding the lengths of all four sides.
Perimeter = Sum of the lengths of the opposite sides + Sum of the lengths of the other opposite sides
Perimeter = 100 feet + 40 feet = 140 feet

Problem: A landscaper plans to reduce the length of the rectangular garden to 15 feet while keeping the width the same. What will the new perimeter of the garden be?

Claude-3 Sonnet:

To find the new perimeter of the rectangular garden, we need to use the new length and the given width.

Given information:
- New length of the rectangle (garden) = 15 feet
- Width of the rectangle (garden) = 20 feet (unchanged)

Step 1: Find the sum of the lengths of the opposite sides.
Length of the opposite sides = 15 feet + 15 feet = 30 feet

Step 2: Find the sum of the lengths of the other opposite sides.
Length of the other opposite sides = 20 feet + 20 feet = 40 feet

Step 3: Find the new perimeter by adding the lengths of all four sides.
New perimeter = Sum of the lengths of the opposite sides + Sum of the lengths of the other opposite sides
New perimeter = 30 feet + 40 feet = 70 feet

Problem: Suppose the side of the rectangle previously mentioned gets extended to 35m instead of 29m, while the other side remains 28m. What would be the new area of the rectangle in this case?

Claude-3 Sonnet:

Okay, let's solve this step-by-step:

Given:
- One side of the rectangle is 28 meters long (this side remains the same)
- The other side of the rectangle is now 35 meters long (instead of 29 meters)

To find the area of a rectangle, we multiply the length and width.

Area of a rectangle = length × width
Area of the new rectangle = 28 meters × 35 meters
Area of the new rectangle = 980 square meters

Therefore, if one side of the rectangle is extended from 29 meters to 35 meters while the other side remains 28 meters, the new area of the rectangle would be 980 square meters.

### Answer: 980 square meters

🔗 Problem

Problem: A rectangle has one side of length 45m and another side of length 47m. Find the perimeter of the rectangle.

Claude-3 Sonnet:

To find the perimeter of a rectangle, we need to add the lengths of all four sides.

Given information:
- One side of the rectangle has a length of 45 meters (m).
- Another side of the rectangle has a length of 47 meters (m).

Since a rectangle has two pairs of equal sides, the other two sides have the same lengths as the given sides.

Step 1: Find the sum of the lengths of the two pairs of equal sides.
Length of one pair of equal sides = 45 m + 45 m = 90 m
Length of the other pair of equal sides = 47 m + 47 m = 94 m

Step 2: Find the perimeter by adding the lengths of all four sides.
Perimeter of the rectangle = Length of one pair of equal sides + Length of the other pair of equal sides
Perimeter of the rectangle = 90 m + 94 m = 184 m

### Answer: 184

Problem: Suppose the length of one side of the rectangle is altered from 47m to 46m. What would be the new perimeter of the rectangle now?

Claude-3 Sonnet:

Okay, let's recalculate the perimeter of the rectangle with the new side length of 46 meters.

Given information:
- One side of the rectangle has a length of 45 meters (m).
- The other side of the rectangle has a length of 46 meters (m).

Step 1: Find the sum of the lengths of the two pairs of equal sides.
Length of one pair of equal sides = 45 m + 45 m = 90 m
Length of the other pair of equal sides = 46 m + 46 m = 92 m

Step 2: Find the perimeter by adding the lengths of all four sides.
Perimeter of the rectangle = Length of one pair of equal sides + Length of the other pair of equal sides
Perimeter of the rectangle = 90 m + 92 m = 182 m

🔗 Problem

Problem: Given a rectangle where the length is 24m and the width is 20m, what is the perimeter of this rectangle?

Claude-3 Sonnet:

To find the perimeter of a rectangle, we need to add the lengths of all four sides.

Given information:
- Length of the rectangle = 24 meters (m)
- Width of the rectangle = 20 meters (m)

The formula for the perimeter of a rectangle is:
Perimeter = 2 × (length + width)

Substituting the given values, we get:
Perimeter = 2 × (24 m + 20 m)
Perimeter = 2 × 44 m
Perimeter = 88 m

Therefore, the perimeter of the rectangle with a length of 24 meters and a width of 20 meters is 88 meters.

### Answer: 88

🔗 Follow-up

Problem: Continuing from the previous scenario, imagine the length of the rectangle stayed the same at 24m, but the width was reduced to 17m. Now, what would be the new perimeter of this rectangle?

Claude-3 Sonnet:

In the previous scenario, we had:
Length of the rectangle = 24 meters (m)
Width of the rectangle = 20 meters (m)

Now, the new information is:
Length of the rectangle = 24 meters (m) (unchanged)
Width of the rectangle = 17 meters (m) (reduced from 20 meters)

To find the new perimeter, we use the same formula:
Perimeter = 2 × (length + width)

Substituting the new values, we get:
Perimeter = 2 × (24 m + 17 m)
Perimeter = 2 × 41 m
Perimeter = 82 m

Therefore, with the length remaining at 24 meters and the width reduced to 17 meters, the new perimeter of the rectangle is 82 meters.
