Question

Find the area of the shape below

Answer 1

230 cm^2

Explanation:

we divide the figure into two figures, a triangle and a rectangle, the height of the triangle is 9 cm ( 16 - 7 = 9), we find the area of ​​the triangle with the formula A = 1/2bh, 1/2 20 x 9 = 90cm^2.

Now we find the area of ​​the rectangle with the formula A = W x L, A = 20 x 7 = 140 cm^2, finally we add the two areas, 90 + 140 = 230 cm^2

Answer 2

The area of this pentagon is

20(7) + (1/2)(20)(9) = 140 + 90 = 230 cm²
