9-123.

Where can you draw a dividing line so that a rectangle

and a triangle are formed?

We need to know the length of the dividing line in order to find the area of the rectangle.

The line is also the hypotenuse for the triangle.

How can we find the length of the hypotenuse of a triangle if we are given both legs?
