The sides of a rectangle are 15cm and 7cm long. How far is the point of the diagonal cross section from the sides of this rectangle?
please include explanation

See below in bold.

Step-by-step explanation:

If we draw a line from the point of intersection to the longest side of the rectangle it will meet it at the midpoint.

The same thing will happen when the line is draw to the shortest side.

So the point of intersection is  1/2 * 7 = 3.5 cm from the longest side and 15/2 = 7.5 cm from the shortest side.
