(please solve with explaination​)

(ps to people who just want points: don't give useless answers)​

Answer 1

Step-by-step explanation:

the most important thing in this question is to find the radius of the circle and as you have marked already it will be the diagonal of the square so the radius will be

14√2 cm

now we can easily find the area of the quadrant of circle = π *r*r/ 4 = 22* 14√2*14√2/ ( 7*4)

= 22*14 = 308 cm ^2

now find the area of square that is 14*14 = 196 cm^2

so area of remaining part = 308-196 = 112 cm ^2
