Answer 2

Answer:

area of shaded portion = 500 cm...

Step-by-step explanation:

here AD acts as a base of triangle and AD = BC = 20 (opposite sides of rectangle are equal. 10 cm is the height.

and

area of shaded portion = area of rectangle - area of triangle

area of rectangle = l x b = 20 x 30 = 600

area of triangle = 1/2 * base x height  = 1/2 * AD * 10 = 1/2 * 20 * 10 = 100

area of shaded portion = area of rectangle - area of triangle = 600 - 100 = 500 cm..
