Find the ar

Answer :


• Square ABCD with side 12 cm

• 4 quarter circles on each of the four vertices, each with a radius(r) 6 cm

Required Area = Ar(PQRS)

(area enclosed within red arcs)

= Area of Square ABCD – Area of Four quarter circles

= Area of Square(side 12cm) – Area of a full circle (radius 6cm)

= (12×12) – π(6)2

(Area of Square = (Side)2 ; Area of Circle = πr2)

= 144 – 3.14(36)

= 144 - 113.04 cm2

= 30.96 cm2
