We can set up a proportion to find the wall area that could be covered with 18 gallons of paint.
9 gallons of paint covers 1125 square feet of wall area.
Let "x" be the wall area that could be covered with 18 gallons of paint.
Using the proportion: 9 gallons / 1125 sq ft = 18 gallons / x.
Cross-multiplying, we get: 9x = 18 * 1125.
Simplifying the right side of the equation: 9x = 20250.
Dividing both sides by 9, we find: x = 2250.
Therefore, 18 gallons of paint could cover 2250 square feet of wall area.
