Curious (Updated)

func carpetCostCalculator(length length: Int, width: Int, carpetColor: String = "tan") -> Int {

let area = calculateArea(length, width: width)

var price: Int

Not sure why you'd say length twice in the function, where you don't for width, but you say length once during the let statement of area to declare which values it uses to calculate the function, and you make width equal width whereas the first part of the parameter you don't. Let me know if anybody can clarify this up! Thank you in advance,
