The Figure Is Made Up Of Two Identical Quarter Circles And A Rectangle The Length Of The Rectangle Is 35 Cm And Its Breadth Is 20 Cm Find The Perimeter Of The F class=

Sagot :

Area of the middle rectangular section = length x width = 35 x 20 = 700 square cm.

The radius of the circular sections is 25 cm

Area of a full circle is pi x r^2 = 3.14 x 25^2 = 1962.5 square cm.

There are two quarter circles which is 1/2 of a circle. The area of those would be 1962.5/2 = 981.25 square cm.

Total area of the figure = 700 + 981.25 = 1681.25 square cm
