// the height and width of a wall
let height = 120.0 // in inches
let width = 144.0 // in inches
let areaInFeet = (120.0/12) * (144.0/12)

This worked for me. the trick is dividing both values by 12 before multiplying. You have to change "inches" into "feet". Hope this helps!

The best way to answer this challenge is to use the declared constant names 'width' and 'height' passed into the new constant, as opposed to using the numbers they are initially assigned to. Granted, they are declared as constants so the numbers won't change, but this is best practice.

// the height and width of a wall
let height = 120.0 // in inches
let width = 144.0 // in inches

let areaInFeet = (height / 12) * (width / 12)
