Question

Q9. Calculate the area of the shaded region: 12 m 9 m 7.5 m 2 m​

Answer 1

Answer:

33m

Step-by-step explanation:

The inner rectangle's area= length× breadth

length=7.5m

Breadth= 10m(12m-2m)

Therefore, area of inner rectangle = (7.5 ×10)m

= 75m

Area of outer rectangle = length× breadth

length =9m

Breadth=12m

Therefore, area of outer rectangle= (9×12)m

=108m

Therefore, area of shaded region =

area of inner rectangle - area of outer rectangle

=75m-108m

=33m
