0. In given figure, the area of shaded region is
- Option : B
- Explanation : (B) Area of PQRS = 20 × 20
= 400 sq cm
Area of ΔTSU = 1/2 × 10 × 10
=50 sq cm
Area of ΔQUR = 1/2 × 10 × 20
=100 sq cm
And area of ΔPTQ = 1/2 × 10 × 20
=100 sq cm
∴ Area of shaded region = 400 - (50 + 100 + 100)
= 150 sq cm
