Question

in the following figure, PQRS is a square of side 4 cm. Find the area of the shaded square
​

Answer 1

Answer:

Step-by-step explanation:

Total Area = 4 x 4 = 16 cm ^2

The middle circle = πr^2 = 3.14 x 1^2 = 3.14 cm^2

The side circles = πr^2/4 x 4 = 3.14cm^2

Shaded Area = 16 - 3.14 - 3.14

                      = 9. 72cm^2
