The video tutorial explains how to calculate the area of compound shapes by dividing them into simpler rectangles. It demonstrates the process using two examples, first by splitting a shape into two rectangles and calculating their areas, and then by providing a student exercise with a solution walkthrough. The tutorial emphasizes understanding dimensions and using basic arithmetic to find areas.

What defines a compound shape in the context of this lesson?

• A shape made up of multiple circles.

• A shape made up of multiple rectangles.

• A shape made up of multiple triangles.

• A shape made up of multiple squares.
