please reply if anyone knows

Answer 1

First let’s find the height or AB

Area of trapeziums = (sum of || sides)1/2*h

24.5=(10+4)1/2*h

24.5=14/2*h

24.5 =7h

H = 24.5/7

H = 3.5

Area of quadrant = 22/7*r^2/4

= 22/7*3.5*3.5/4

= 9.625

Area of shaded region = area of trapezium - area of quadrant

= 24.5 - 9.625

= 14.875 cm
