The perimeter of a rectangle is 360 feet, and the length of the rectangle is thrice the width.

Question

Find the dimensions of the rectangle.

Answer 1

P = 2L + 2W = 2(L+W) = 360

 

L + W = 180

L = 3W

 

3W + W = 180

4W = 180

 

Finish solving for w to find width.

Then us L = 3W to find the length
