Draw the rectangle !

Let's call L and h the sides of the rectangle.

What we have is 2*(L+h) = 10 (or L+h = 5).

Now look at your drawing. Your rectangle has right angles. You can build interesting triangles with that (and the diagonal) and use a certain theorem that you probably know.

If you’re going to make variables and an equation, you might as well make both equations:

The second eqn comes from using Pythagorean Theorem on the triangle you get if you slice your rectangle along a diagonal.

Try to find L and H that solve those two equations. (Hint: H = L – 5, and you can use that to rewrite Eqn 2 in terms of just L.)
