Find the area of Fig. 20.35 as the sum of the areas of two trapezium and a rectangle.

Area of figure = Area of two trapeziums + area of rectangle

Length of rectangle = 50 cm

Breadth of rectangle = 10 cm

Length of parallel sides of trapezium = 30 cm and 10 cm

Distance between parallel sides of trapezium =

Area of figure =

Area of figure = 2 ×

Area of figure = 400 = 900 cm^{2}
