Had some problems getting this correct. could someone show me what the code should look like and/or explain why.

the task states: Given the height and width of a wall in inches, calculate the area in feet and assign it to a constant named areaInFeet.

the initial code given is

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

below is your code:

let height = 10.0 // in feet
let width = 12.0 // in feet


let areaInFeet = height / width

you hardcoded the values in feet, however you are expected to use swift operators to do that.

You need to calculate the area in feet. the general formula for the area of a rectangle is A=wl, in our case its A=wh since its a wall. In your code you computed the quotient instead of the product which is why it told you your value was incorrect

To get the area in feet (well technically square feet), you can compute the product of the height constant converted to feet and the width constant converted to feet. Since there are 12 inches in a foot we can divide the height and width in inches by 12 to get their values from inches and into feet.

let height = 120.0 // in inches
let width = 144.0 // in inches
let areaInFeet = (height / 12) * (width / 12)

The answer is very easy you do not have to do the answers above

You need to read the instructions carefully digest the information slowly then proceed

When it give you the height and width

let height = 120.0 // in inches convert them to feet you get 10.0 let width = 144.0 // in inches convert them to feet you get 12.0

let areaInFeet = 120.0
