Need some help :(

Homework Statement



One side of a rectangle is 5meters shorter than the other. If the length of the diagonal os 14m, find the lengths of the sides

Homework Equations





The Attempt at a Solution



This is a question we haven't been equipt to answer, so I really need some help. All I have come up with is a bad attempt with Pythagoras:

Trying to do 14^2=(a-5)^2+b^ and somehow get a value. Obviously, I've come up with nothing :(

You don't need both "a" and "b" for the two sides. You know one side is 5m shorter than the other, so just use "a" again in the last term on the righthand side (RHS) of your equation, and then solve for a...
