how do i figure out the proper value for the constant?

i know its something simple.

area.swift
// the height and width of a wall
let height = 120.0 // in inches
let width = 144.0 // in inches

let area = height * width
let areaInFeet = area / 120

1 Answer

You only need one statement to accomplish this. Since area = height x width, the area in feet would have to be the height in inches divided by 12, multiplied by the width in inches divided by 12.

// 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)
