The length of a rectangle is six times its width. If the area of the rectangle is 600 m2 , find its perimeter.

Answer 1

L = 6W

 

Area A = LW = 600. So, 6W(W) = 600, W² = 600/6 = 100, so W = 10. Then L = 600/10 = 60.

 

Perimeter P = 2L + 2W = 2(60) + 2(10) = 120 + 20 = 140.

 

There are other ways to set this up, but this works well enough.
