Wrong calculation

[incredibleLeitman]

Although this is not really a programming issue,
but your cost calculations are not correct:

projectOne/ConsoleApplication1/Program.cs

Line 71 in ac5fc85

double totalCost = calculateShape / SQUARE_FEET * cost;

If the user has an area of x square feet and the price for one square foot is y,
the total material cost would be just "x * y"

You could also add the total cost, combining material and labour cost and present it to the user :D
