// 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

Dont put quotation marks around variable names...this way you make these names to some Strings. And you can not devide a String with an integer. height is not the same as "height". Also your calculation was not complete.
