Apainter uses 1.2 liters of the paint to cover 1m2 of the wall. how much paint will he need to cover 0.5m2?

0.6 liters paint will he need to cover

Step-by-step explanation:

Direct Variation states that the two quantities are related in such a way that  increase in one quantity results in a corresponding increase in the other quantity and vice versa, then such type of a variation is called a direct variation.

i.e

It is given that the painter uses 1.2 liters of paint to cover

This is the situation of Direct Variation:  As less area cover, less liters of paint.

Let two quantities are x  and y;

x represents the area covered by painter

y represents the liters uses by the painter.

Then, the ratio of any two values of y is equal to the corresponding value of x.

i.e,

or

therefore, from the given information we have;

Simplify:

Therefore, 0.5 liters paint required by the painter to cover the area
