1. Многоугольник на рисунке разбит на два прямоугольника. Вычислите площадь фигуры.

The figure is composed of two rectangles. The larger rectangle has dimensions 3 cm x 3 cm, and the smaller rectangle has dimensions 1 cm x 2 cm.

Area of the larger rectangle = 3 cm * 3 cm = 9 cm².

Area of the smaller rectangle = 1 cm * 2 cm = 2 cm².

Total area = 9 cm² + 2 cm² = 11 cm².
