a baseball diamond has the shape of a square 90 feet on each side . The pitcher's mound is 60.5 feet from homeplate on the segment joining home plate and second base. Find the distance from the pitcher's mound to second base to the nearest tenth of a foot.

Okay so do you have to draw a square and then divide diagonally to create two right triangles?
I dont know what else to do and how to draw the diagram and do this problem. Please help !
