Question

Q.10 Find area of shaded region in given figure
​

Answer 1

Step-by-step explanation:

length of outer rectangle=12m

breadth of outer rectangle=12m

area of outer rectangle=lxb

=12m x 12m

=144m²

length of inner rectangle=12-3-3

=6m

breadth of inner rectangle=12-4-4

=4m

area of inner rectangle=lxb

=6m x 4m

=24m²

area of shaded region=area of outer rectangle-area of inner rectangle

=144m²-24m²

=120m²

so area of shaded region is 120m².
