Question

ABCD and PBQT are square of side 10cm and 3cm resp 3.5=DS​

Answer 1

Step-by-step explanation:

Area of square ABCD = 10*10 = 100 cm. sq.

Area of square PBQT = 3*3 = 9 cm sq.

Area of quadrant circle RDS =

22/7 * 3.5 * 3.5 * 1/4

= 38.5 * 1/4 = 9.625cm sq.

shaded area = area of square ABCD - (area of square PBQT + area of quadrant circle)

= 100 - (9 + 9.625)

= 100 - 18.625 = 81.375 cm. sq.

Shaded area = 81.375 cm. sq.
