Final answer:
To cover 5.8 square meters of wall, the painter will need approximately 6.96 liters of paint.
Step-by-step explanation:
To find out how much paint the painter will need to cover 5.8 square meters of wall, we can use the given information that the painter uses 1.2 liters of paint to cover 1 square meter. We can set up a proportion to solve for the amount of paint needed:
1.2 liters / 1 square meter = x liters / 5.8 square meters
To solve for x, we cross-multiply and divide:
1.2 * 5.8 = x
x = 6.96 liters
Therefore, the painter will need approximately 6.96 liters of paint to cover 5.8 square meters of wall.
