Question

Ek Dor of dimensions 3 metre into 2 metre is on the wall of dimensions 10 metre into 10 metre find the cost of painting the wall if rate of painting is rupees 2.50 per square metre​

Answer 1

Answer:

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.

Hope it helps

Answer 2

SOLUTION :

Area of door = Length × Breadth

= L × B

= 3 m × 2 m

= 6 m^2

Area of wall including door = Length × Breadth

= L × B

= 10 m × 10 m

= 100 m^2

Area of wall excluding door = 100 - 6

= 94 m^2

Total labour charges for painting the wall is

= 2.50 × 94

= Rs. 235
