Question

12. In the given figure, find the area of the shaded portion.
35 cm
10 cm​

Answer 1

solution ;

area of square = $a ^{2} \\ = (10) ^{2} \\ = 100$

now

area of circle =π$r ^{2} \\ \frac{22}{7} \times 7 \\ = 22$

find the shaded region = area of square-area of circle

$100 - 22 = 78$

hence; area of shaded region = 78 cm
