Question

A rectangle is  times as long as it is wide. The perimeter is  feet. Find the dimensions.The length is  feet where the width is  feet.

Answer 1

Hi Marnie, let l represent the length of the rectangle and w represent the width of the rectangle.

The perimeter of the rectangle is given by:

p = 2l + 2w

Given:

The length is equal to seven times the width.

Equation to solve:

64 = 2 * 7w + 2w

64 = 14w + 2w

64 = 16w

w = 4

The width of the rectangle is 4 feet.

The length of the rectangle is 28 feet, or length = 4 * 7.
