Question 831961: what is the length and width of a rectangle with a perimeter of 135 feet. the ratio of length to width is 8:1 Answer by JulietG(1812) (Show Source):
You can put this solution on YOUR website! The perimeter is the fence around. P = 2L + 2W
What we're told in the question is:
135 = 2L + 2W
L = 8W (the ratio of length to width is 8:1)
Plug that value into the initial equation
135 = 2(8W) + 2W
Multiply
135 = 16W + 2W
Add
135 = 18W
Divide each side by 18
7.5 = Width
.
If the width is 7.5, then the length is 8 * 7.5, or 60
Let's see if that works.
2 length (60+60) + 2 width (7.5+7.5) = 135
120 + 15 does indeed equal 135.
success!
