Question

Find the area of the shaded portion.All corners are right angled.​

Answer 1

Answer:

Area of bigger rec. =l*b

=15 *19.6=294 m^2

Breadth of smaller rec. =15-2-2

=15-4

=11m

Length of smaller rec. =19.6-5.4=14.2m

Area of smaller rec. =l*b

=14.2*11

=156.2 m^2

Area of shaded portion

=294-156.2=137.8 m^2
