I am guessing that 9 x 12 feet tell me the measurement of the wall and that there are four walls?
Paint: 400 sq ft
Wall paper: 3 rolls of 5 yards (60 ft) = 180 ft
Mark 9 ft x 12 ft
Area = 108 * 4 = 432 sq ft
Perimeter = 4*12 = 48 ft
Mark has enough wall paper.
Maria 10 ft x 12 ft
Area = 120 * 4 = 480 sq ft
Perimeter = 4*12 = 48 ft
Maria has enough wall paper.
David 12 ft x 12 ft
Area = 144 * 4 = 576 sq ft
Perimeter = 4*12 = 48 ft
David has enough wall paper.
Obviously, they all do not have enough paint ....
Also, they all have enough wall paper ....
