I dont understand why my answer comes up as a bummer for areaInFeet Challenge.

let height = 120.0 let width = 144.0

let area = height * width

Let areaInFeet = area /12

area.swift
// the height and width of a wall
let height = 120.0 / 10
let width = 144.0 / 12

let area = height * width

let areaInFeet = area 

You're dividing height by 10 not 12

Thanks the response, I tried 12 as well in my code and it still came up. Bummer

Hello David :

Here is what you are looking for

let height = 120.0 / 12 
let width = 144.0 / 12

let areaInFeet =  height * width 

what you were trying to do also works...

let height = 120.0 / 12
let width = 144.0 / 12

let area = height * width 
let areaInFeet = area 

Thanks Johan

That was the best answer
