Question

Help please!!! Find the area of the shaded region. All angles are right angles

Answer 1

Area =
`147 m^(2)`

Explanation:

The area of the shaded region is equal to the total area of the full square minus the area of the non shaded region.

The area of a rectangle is its base times its high

So A=b*a.

For the full square, A1=
`9m*23m=207m^(2)`

For the non shaded square, A2 =
`15m * 4m = 60m^(2)`

So the shaded area is A1-A2 =
`207 m^(2) -60 m^(2) = 147 m^(2)`
