The width of a rectangle is 4 times the length. The Perimeter of the rectangle is 30 ft. What is the Area of the Rectangle?

Question

I was just wondering what's the algebraic equation to help solve this. Thanks!

Answer 1

L = Length; W = width = 4L

Perimeter = 2(L + W) = 2(L + 4L) = 10 L = 30 => L = 3 and W = 12

Area = L * W = 36
