In the figure given below, find the area of shaded region: (All measurements are in cm)
Advertisements
Solution
Outer length = 30 cm
and Outer breadth = 20 cm
∴ Outer area = l × b
= 30 × 20 = 600 cm2
Inner length = 12 cm and inner breadth = 12 cm
Inner area = l × b = 12 × 12 = 144 cm2
Area of shaded portion = Area of outer figure − Area of inner figure
= 600 − 144 = 456 cm2
