What is the wrong thing about this...Help

I did everything i could but the preview tells me to remove the "h" on the last line(e.g. let areaInFeet = h <- ieght) it tells me to remove it...again...help

I would appreciate it if you could help me.

area.swift 
// the height and width of a wall
let height = 120.0 // in inches
let width = 144.0 // in inches
let areaInFeet = height(120.0) + width(144.0) = 164.0

Finding the area requires multiplication not addition, like below:

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

let areaInFeet = height * width
