Question

if a square OABC is inscribed in a quadrant OPBQ . If OA =20cm find the area of shaded region​

Answer 1

Answer:

228cm2

Step-by-step explanation:

Using phytagorus theorem

H=√l^2+b^2

H=20√2cm

the area of square=side ×side

=400cm

the area of the fourth part of circle=1/4πr^2

= 628cm

the area of shaded region=Area of circle's fourth part - area of square

=228cm
