Question

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?

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

The cost of labour for painting the wall will be 300 rupees.
