Problema Solution

I had a problem that showed a rectangle which gave the width and length but had a diagonal line thru it and it asked the length of that. What formula do I use for that? I am lost. Thank you. Patti

let


w = width


l = length


d = diagonal


you should Pythagorean Theorem that is:


d^2 = w^2 + l^2
