you need to divide the height and width by 12. therefore your code should look like this

let aeraInFeet = height/12 * width/12

i tried this code and it seems to be incorrect

It needs to be like this:

// 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)
