Question

A rectangle has dimensions of 8 in by 13 in. If the larger side is doubled, how will that change the perimeter of the rectangle?

a) The perimeter will double.
b) The perimeter will be 4 times as much.
c) The perimeter will increase by 13 inches.
d) The perimeter will increase by 26 inches.

Answer 1

The perimeter of the rectangle will increase by 16 inches. None of the options is correct

Step-by-step explanation:

The dimensions of the larger rectangle are 16 inches by 13 inches, since the larger side is doubled. To calculate the perimeter of the rectangle, you add up the lengths of all four sides. For the original rectangle, the perimeter is 2(8+13) = 42 inches. For the larger rectangle, the perimeter is 2(16+13) = 58 inches. So, the perimeter increased by 16 inches, which is the same as the length of the larger side.
