Question

In the given figure, OABC is a square of side 7 cm. If COPB is a quadrant of a circle with centre C find the area of the shaded region.

Answer 1

Area of shaded region = Area of square OABC − Area of quadrant COPB having radius OC

`= (Side)^2 - 1/4(pixx"r"^2)`

`=(7)^2 - 1/4[22/7xx7^2]`

= 49 - 38.5

= 10.5 cm² 

Area of shaded region = Area of square OABC − Area of quadrant COPB having radius OC
