What is the area of this shape?!

The area of the figure presented in the image, which is formed by one right triangle and three rectangles is equal to an amount of 157 square kilometers. How to determine the area of a compound shapeIn this question we understand that the area of the compound shape is the sum of the area of small rectangles and triangles:[tex]A = \sum \limits^{n}_{i = 1} A_{i}[/tex]     (1)Now we proceed to calculate the area of the compound shape:A = 0.5 · (4 km) · (3 km) + (10 km) · (2 km) + (17 km) · (7 km) + (2 km) · (6 km)A = 157 km²The area of the figure presented in the image, which is formed by one right triangle and three rectangles is equal to an amount of 157 square kilometers.
