how to type the formula?

i don't know how to type the calculation since i need to convert the inch numbers to square feet, what is the code for that?

area.swift
// 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

Daniel Koo you're very close here! Here's the line you're looking for:

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

First we take height and divide it by 12 to give us the height in feet. Then we take the width and divide it by 12 to give the width in feet. Then we multiply those two together to get the area in feet, which is assigned back into areaInFeet. Happy coding! :sparkles:
