Question

in the adjoining figure find more he area of shaded region​

Answer 1

So this figure forms a square

side = 20

Area = 20 × 20

Area = 400

Area of the trapezium at the right side of the figure

Area of Trapezium= 1/2(a+b)h

Area = 180

Area of the Triangle at the bottom left of the figure

Area of triangle=1/2(b×h)

Area = 31.5

Area of another triangle = 1/2(11×7)= 38.5

Area of shaded region = Area of the whole figure - Area of Unshaded region

400-250= 150
