**Helper**, Tuesday, March 15, 2011 at 9:58pmYour question, I assume, is to find the length and width of the rectangle?

The diagonal creates 2 right triangles.

L = length

L - 4 = width

By the Pythagorean theorem,

d^2 = L^2 + (L - 4)^2

20^2 = L^2 + (L - 4)^2

Solve for L, the length

width = L - 4
