The area of the room in square feet is found, as Raimi says, by multiplying the length in feet times the width in feet. As a formula, this looks like

A = L*W.

So the problem, in part, is to express the dimensions as feet. One way is to write them as a mixed fraction:

L = 16 9/12 feet = 16 3/4 feet = 16.75 feet

W = 13 11/12 feet = 13.91666... Feet.

Then

A = L*W = (16.75)*(13.9167) = 233.104... Square feet

The remainder of the problem is to find the price. This is similar to a units conversion problem. Here we are converting square feet to dollars.

Price = A * (.25 dollars/square foot)

Price = 233.10 square foot * .25 dollars/square foot = $58.28.

If your store only sells whole numbers of square feet of flooring, your cost may be 234*.25 = $58.50.
