Question

ple: A wall that is 4 m long and 3 m wide has to be painted. If the labour charges are 25
per sq m, what is the cost of labour for painting this wall? What is the cost of painting 4
such walls?​

Answer 1

First ,

let us calculate the area of the wall to be painted.

Area of the wall = length of the wall × breadth of the wall

= 4 × 3 = 12

Thus, the area of the wall is 12 sq m.

Labour cost of 1 sq m is 25 rupees.

So , the labour cost for 12 sq m will be = 12 × 25 = 300 rs

Therefore, cost of painting such a four wall is

4×300 = 1200rs
