C

Step-by-step explanation:

First find the area of the entire figure.

L= 36

W = 20

Area = 36 * 20 = 720

Find the area of the left right triangle.

Height = 20

Base = 1/2 * 36 = 18

Just as an aside, let me be a little grumpy for a moment. You should never have to guess what a dimension is on a diagram. It's sloppy. However for this problem you have no choice. But you could think to complain to your teacher.

Area = 1/2 * base * height

Area = 1/2 * 18 * 20 = 180

Find the area of the bottom right triangle.

The height is 1/2 20 = 10

The base is 36

Area of the lower triangle = 1/2 * 36 * 10 = 180

Area of the shaded figure = 720 - 180 - 180 = 360

- 70

this is the answer for you hope it

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
