Sol: Area of the trapezium = h/2 (a + b) where a and b are the parallel sides and h is the perpendicualr distance between the parallel sides. Area of the trapezium ABCD = AB/2 (AD + BC) 24.5 = (AB/2) (10 + 4) 49 = AB (14) AB = 3.5 cm Radius of the quadrant of the circle = AB = 3.5 cmArea of the quadrant of the circle = (1/4) (πr2) = (1/4) (22/7 x 3.5 x 3.5) = 9.625 cm2 Area of the shaded region = Area of the trapezium - Area of the quadrant of the circle                                       = 24.5 - 9.625                                       = 14.875 cm2
