Question

The length of a rectangle is twice its width. the perimeter of the rectanhle i 126 feet

Answer 1

Hi there!

Let the width of the rectangle be called x. Then the length of the rectangle is 2x. We get the following perimeter:


`x + x + 2x + 2x = 126`
Collect the terms


`6x = 126`
Divide by 6


`x = 126 / 6 = 21`
Therefore, the width of the rectangle is 21 feet and the length is 2 × 21 = 42 feet.
