Answer:
Area = [tex]147 m^{2}[/tex]
Step-by-step 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=[tex]9m*23m=207m^{2}[/tex]
For the non shaded square, A2 = [tex]15m * 4m = 60m^{2}[/tex]
So the shaded area is A1-A2 = [tex]207 m^{2} -60 m^{2} = 147 m^{2}[/tex]
