In the diagram on the right, each of the squares touches adjacent squares at the corners and the line GH along one of the edges. If the length of GH is 24cm, what is the total perimeter of all the squares?

What is the area of triangle abc if a = 8, b = 11, and c = 15?

Name each raycalculation tip: in ray "ab", a is the endpoint of the ray.
