Question

total cost of painting a wall is ₹10 per sq m is ₹1000 find the breadth of the wall if its length is 20m

Answer 1

Answer:

cost of painting a wall is ₹10 per square m is ₹1000

so, area of wall= ₹1000/₹10 per sq m

=100 sq m

let breadth of wall = b

so, 20m *b= 100 sq m

b= 100sq m /20m

therefore breadth= 5 m
