Find the area of the shaded section.
3 cm
9 cm
7 cm
16cm​

The area of the shaded portion is 123 cm^2

Step-by-step explanation:

Here, we want to find the area of the shaded portion

To find this, we subtract the area of the smaller inner rectangle from that of the outside bigger one

Mathematically, the area of a rectangle at any point in time is length * width

For the bigger one, we have;16 * 9 = 144 cm^2

For the smaller inner one, we have ;3 * 7 = 21 cm^2

The area of the shaded portion which is the difference is;

144-21 = 123 cm^2

take the top number and divide it by a the bottom number

step-by-step explanation:

1/2 1 divied by 2 = .5

center= (-2,0)

radius= sqrt2/2
