Look at just the left half of the diagram for now. You have a right triangle and you have the measures of 2 sides, so you can use the Pythagorean Theorem: x^2 + 12^2 = 13^2 You can get x^2 from that and then get "x" Your perimeter will be easy from there.

Well, first, you have to solve: x^2 + 12^2 = 13^2

Hint: subtract 12^2 from each side.

Don't worry, I'll help you: (x^2 + 12^2)  12^2 = 13^2  12^2 x^2 + (12^2  12^2) = 13^2  12^2
