1. You have that 1 m² is convered with 1.2 liters of paint.
2. Therefore, to solve this problem, you can calculate the liters needed to cover 7 m² by multiplying this area by 1.2 liters and dividing this by 1 m², as you can see below:
Let's call the liters needed to cover 7 m² [tex]x[/tex], then you have the following result:
[tex]x=\frac{(7m^{2})(1.2L)}{1m^{2}}\\x=8.4L[/tex]
