I watched the video, but I am not really understanding what its asking. Could use some tips.
// the height and width of a wall
let height = 120.0 // in inches
let width = 144.0 // in inches
let areaInFeet = height * width / 12

You are really close but just need to specify dividing by 12. The way you have it now, you are simply dividing the width by 12 but you must divide both width & height. So your final constant should look like this:
let areaInFeet = (height / 12) * (width / 12)
I hope this helps =)
