you need to divide width and height by 12 (because there are 12 inches in a foot), and then multiply width in feet by height in feet (because to find the square footage, you use base x height = area).

hope this helps!

Thanks this is my code: It still won't work.

let height = 120.0 // in inches

let width = 144.0 // in inches

let area = height * width

let areaInFeet = area / 12

It says areaInFeet has the wrong value.

they actually want you to do this:

area = (height / 12) * (width / 12);  // = 120 sq ft.

because if you do it your way: 

height * width = 17280 inches 

17280 / 12 = 1440 sq ft...
