d. ₹ 252.50​

Answer 1

Answer:

Dimension of Door = 4m × 5m

Area = Length × Breadth

= 4m × 5m

= 20m²

Dimention of wall = 11m × 11m

Area = Side × Side

= 11 × 11

= 121m²

Area left for painting = Area of Wall-Area of Door

= 121m² - 20m²

= 101m²

Cost for painting 1m² = ₹2.50

Then,

Cost for painting 101m² = 101×2.50

= ₹252.50
