Question

A plot is in the form of a rectangle PQRS having semi-circle on PQ.if PS-80M and SR-35 m,find the area of the plot.

Answer 1

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
