Step-by-step explanation:
Area of shaded =Area of Outer rectangle - Area of Inner rectangle.
Area of inner rectangle = L× B.
L=18
B=11
Area of inner rectangle = 18×11
=198m^2
To find the full breadth of the outer rectangle
=2 in +11 + 2 in
=15
To find the full length of the outer rectangle
=2 in + 18 + 2 in
=22
Area= 22 × 15
Area = 330m^2
Area of shaded portion = 330 - 198
=132m^2
