Question

the perimeter of the rectangle is 96 when the length of a rectangle is twice the width.​

Answer 1

Answer:

Let's review the formula for perimeter of a rectangle: 2l + 2w = P. Given this, we will let width be x and length be 2x and substitute the values into the equation as w and l, respectively.

2l + 2w = P

2(2x) + 2x = 96

4x + 2x = 96

6x = 96

x = 16

The length of the rectangle is 2x = 2(16) = 32 cm

Answer 2

x = 16
