Question

In the given figure there is a square of side 14 cm. Find the area of the shaded region
by the area of the track
-14 cm​

Answer 1

Step-by-step explanation:

Area of semicircle =

2

πr

=77 cm

{Diameter=14}

Area of c

=

2

π(7)

=77 cm

2

Area of rectangle ABDB =l×b=14×8=112cm

2

Area of shaded region =A(ABDC)−A(c

1

+A(c

2

))

=A(ABDC)=112cm

.

Perimeter of semicircle =πr

Perimeter of shaded region =πr

=π(7+7)+16=14π+16

=44+16=60 cm
