place answer my question​

Answer 1

Answer:

86 cm *2

Step-by-step explanation:

In the quadrant OPBQ,

Area = pie × radius square.

radius = side of the square = 20 cm

so, area = 3.14 × 20 cm*2

= 314 × 20 cm*2

100

solving you can get, 314 cm *2.

Now in the square,

side= 20 cm

area = side × side

20 × 20 cm*2

400 cm*2

so, area of the shaded region = 400 cm*2 - 314 cm*2

= 86 cm*2
