Find the area of the figure:
astra-53 [7]

Answer:

To find the area of she shaded part we first need to find the total of the area.

L x W

8 x 5 = 40 is the total area

Now we need to find the area of the non - shaded part

Since it is a square all sides are equal the short lines sticking from the sides indicate that

2 x 2 = 4

Now we subtract the total area from the non shaded area.

40 - 4 = 36
