Question

Total cost of whitewashing a wall at Rs25 per sq m is Rs12150. If the length of the wall is 27 m find the breadth

Answer 1

Cost of whitewashing = area × Rs25 per sq m

12150 = area × 25
2150/25 = area
486 sq m = area

Area = l × b
486 = 27 × b
486/27 = b
18 = b

Breadth = 18 m

Answer 2

Answer:

18 m

Step-by-step explanation:

Cost of whitewashing = area × Rs25 per sq m

12150 = area × 25

2150/25 = area

486 sq m = area

Area = l × b

486 = 27 × b

486/27 = b

18 = b

Breadth = 18 m
