Question

1. Find the area of the shaded portion in the figure given above

​

Answer 1

Here,

Area of Shaded Portion = Area of trapezoid - Area of rectangle.

∴ Shaded region = ½(a + b)(h) - xy

⟹ Shaded region = ½(60 + 30)(10) - (5)(10) cm²

⟹ Shaded region = 5(90) - 50 cm²

⟹ Shaded region = 450 - 50 cm²

⟹ Shaded region = 400 cm².
