Answer:
Gia will need 2 liters of paint to cover her wall
Step-by-step explanation:
To get this, what we need to do at first is to calculate the area of the wall.
Mathematically since we have a rectangular wall, the area can be calculated by multiplying the length by the breadth.
Thus A = 4 * 5 = 20 M^2
Now from the beginning of the question, we were made to know that 1 liter will cover an area of 10 M^2
Thus, the amount in liters of paint that will cover an area of 20 M^2 will be 2 * 1 = 2 liters
