Which shape has the greatest perimeter if it measures 11 feet on each side?

To determine which shape has the greatest perimeter, it’s essential to calculate the perimeter of each shape based on the given dimensions.

A square that measures 11 feet on each side has a perimeter calculated as follows: Perimeter of a square = 4 × side length. Therefore, the perimeter is 4 × 11 feet, which equals 44 feet.

For the rectangle measuring 11 feet by 9 feet, the perimeter is calculated by adding twice the length and twice the width: Perimeter = 2(length + width) = 2(11 + 9) = 2 × 20 = 40 feet.

For the triangle with all sides measuring 11 feet, the perimeter is simply the sum of all sides: Perimeter = 11 + 11 + 11 = 33 feet.

The circle with a diameter of 11 feet requires calculating the circumference using the formula: Circumference = π × diameter. Therefore, the circumference is approximately 3.14 × 11 feet, which equals about 34.54 feet.

When comparing all these perimeters:

• The square has a perimeter of 44 feet.
• The rectangle has a perimeter of 40 feet.
• The triangle has a perimeter of
