(1.25)(2.75)(65000)/144 in^2/ft^2 =

223437.5 in^2/144 in^2/ft.^2 =

1551.6 ft^2......answer

Since they are inversely proportional
12/1551.6 = 18/x
12x = 27928.8
x = 2327.4 ft^2.......answer

area in square inches: 65000(1.25)(2.75) = 223,437.5

area is square feet: 223437.5 / 144 = 1,551.65

(If you're wondering where the 144 came from, that's the number of square inches in a square foot. Multiply 12 by 12 to get 144).

If the efficiency was only 12%, then you need to solve the following equation for x, which is the total area needed:

.18(1551.65) = .12x

x = (.18/.12)(1551.65) = 2327.475

which is 775.825 square feet more than 1551.65.
