We solve several geometry problems involving the area of rectangles. In the first one, we have a rectangular shape that needs divided into two parts in order to find its area. The second rectangle IS already in several parts, and we find the total area. The last problem asks how much larger is the area of a square with 10 cm sides than the area of a square with 7 cm sides.
