Question

find the area of the shaded region

Answer 1

Area of circle = pi r square
= 22/7 * 13/2 * 13/2
= 1859/14
=132.76

Now area of rectangle = 12*5
= 60
therefore area of shaded plot = 132.76-60
=72.76

Answer 2

ar(rectangle)=LxB=5x12=60

since 12 is a diameter
therefore radius = D/2=12/2=6

ar(circle) πr*2=22/7x6x6=113.14

area of shaded region = area of circle-area of rectangle
= 113.14-60
=53.14
