Answer:
Rs 235
Step-by-step explanation:
Painting of the wall has to be done excluding the area of the door.
Area of the door = L × b
= 3 × 2m² = 6m²
Area of wall including door = side × side = 10 m ×10 m = 100m²
Area of wall excluding door = (100–6) m² = 92m²
Total labour charges = Rs 2.50 × 94
= Rs 235
