determine the area of each of the following figures. assume that all angles that
look like right angles are right angles.

Part a) The area of the figure is

Part b) The area of the figure is

Step-by-step explanation:

Part a) we know that

The area of the figure is equal to the area of rectangle plus the area of trapezoid

step 1

The area of rectangle is

we have

substitute the given values

step 2

The area of trapezoid is

we have

substitute

step 3

Find the area of the figure

substitute

Part b) we know that

The area of the figure is equal to the area of rectangle plus the area of two triangles

step 1

The area of rectangle is

substitute the given values

step 2

The area of triangle at the top is

we have

substitute

step 3

The area of triangle at right is

we have

substitute

step 4

Find the area of the figure

substitute

it’s supposed to be -4+45=41
