प्रश्न
In the figure given below, find the area of shaded region: (All measurements are in cm)
उत्तर
Outer length = 20 cm
and breadth = 16 cm
∴ Outer area = l × b
= 20 × 16 cm2 = 320 cm2
Inner length = 15 cm
and Inner breadth = 10 cm
∴ Inner area = 15 × 10 = 150 cm2
∴ Area of shaded region = Area of whole region − Area of unshaded region
= 320 − 150 cm2 = 170 cm2
