Compare 9 liters to 6 liters.
9/6 = 3/2 = 1.5
So you have 1.5 times as much paint, you would expect to cover 1.5 times as much area.
1.5 * 50 = 75 m²
You could also solve this using a proportion and you should get the same answer.
(area) / (paint) = (area) / (paint)
50/6 = x/9
25/3 = x/9
x = 9 * 25/3
x = (9/3) * 25
x = 3 * 25
x = 75 m²

if you know how much surface area 6 liters of paint covers and you want to know how much surface area 9 liters of paint will cover, you should ask yourself how do I find out how much surface area 1 liter of paint covers.....
that means 6 liters will cover six times as much.
to get from 6 liters to 1 liter divide the surface coverage of 6 liters (50 sq m) by 6
If you know how much surface area 1 liter covers then figuring the coverage of 9 liters is simple multiplication.
(50/6)*9=75 square metersSource(s): how I solved conversion problems in 3rd grade.
