Here, l = 60 m, b = 26 m and r = 282 = 14 m Area of rectangle ABCD = l × b = 60 × 28 = 1680 m^2 radius(r) = BC2 = 282 = 14m Area of semicircle = pir^22 ... More

area of rectangle=l×b

=80×35

=2800m square

area of circle=π r square

=22/7 × 35/2 × 35/2

=1925/2m square

area of semicircle=1925/2÷2=1925/4.

Area of plot = area of rectangle +area of semi cirle.

Area of plot=2800+1925/4

=13125/4m squares
