Answers
Given : A gate having dimensions 2m×1m is in the wall of 3m × 5m. If the cost of coloring is Rs 100 per m²,
To find : the cost of colouring wall.
Solution:
wall of 3m × 5m.
Area of the wall = 3 * 5 = 15 m²
gate having dimensions 2m×1m
Area of gate = 2 * 1 = 2 m²
Area of the wall to be painted = Area of the wall - Area of gate
=> Area of the wall to be painted = 15 - 2
=> Area of the wall to be painted = 13 m²
cost of coloring is Rs 100 per m²
Hence cost of coloring wall = 100 * 13 = Rs 1300
