The perimeter of a rectangle is 324 feet. the ration of the width to the length is 1:2. find the length and width of the rectang

hjlf

If the ratio of the width to the length is 1 : 2 then, we can represent their respective lengths using x and 2x.

Width = x
Length = 2x

2(x) + 2(2x) = 324
2x + 4x = 324
6x = 324
x = 54
2x = 108

The width is 54 ft. and the length is 108 feet. Hope this helps!
