Answer 1

Answer:

Rs 546.75

Step-by-step explanation:

For the door, 3.5m x 1.5m = 5.25m².

Therefore area of the wall excluding the door is 66 - 5.25 = 60.75 m².

Now cost of painting, 9 x 60.75 = 546.75.

Answer 2

Answer:

546.75 rupees

Area of the wall = 12m × 5.5m

Area of door = 3.5 × 1.5 m = 5.25m²

66m²- 5.25m²= 60.75m²

cost of per m² = 9 rupees

for 60.75 m² = 60.75 × 9 = 546.75
