Answer: Rs 450

Step-by-step explanation:

Length = 2m, breadth=4m, height=3m

Area of room =2×4×3 m²

= 24 m²

Dimensions of door = 2.5m × 2m

Area = 5m

Dimensions of each window = 2m × 1m

Area of 2 windows = 2 ×2×1 m²

= 4m²

Area of 4 walls = ( 24 - 5 - 4) m²

= 15 m²

Rate of papering = Rs 30 per m²

Cost = Rs ( 30 × 15 ) = Rs 450
