Question

3Calculate the area of the shaded portion .
​

Answer 1

Answer:

246 m²

Step-by-step explanation:

Area of rectangle = l*b

Area of whole fig = 15*20 = 300m²(Resembling a rectangle)

Area of inner rectangle :

l = 20-(7+4) = 20-11 = 9 m

b = 6m

Area = l*b = 6*9 = 54m²

Now Area of shaded = 300-54 = 246 m²
