Question

Joe is a carpenter, whose main source of income is putting vinyl floors, as well as molding around the floor. When a customer wants to put flooring in a specific room and contacts Joe for an estimate, Joe begins by measuring the length and width of the room. Then, he finds out the current unit cost of vinyl (per square foot) and the unit cost of molding (per foot). Once he gets this data, he calculates the total cost of required materials, using the following formulas: area = length × width perimeter = 2 × (length + width) total-cost-of-vinyl = area × unit-cost-of-vinyl total-cost-of-molding = perimeter × unit-cost-of-molding cost-of-materials = total-cost-of-vinyl + total-cost-of-molding. Your task is to help Joe by implementing a program for his calculations. Implement a program that inputs the length and width of a room and computes the area and perimeter of the room. Input and output: Your program should first prompt the user to enter the room length, then prompt the user to enter the room width, and then output the results. We assume that the length and width are integers between 1 and 500 (measured in feet).

00:01 Okay, so i see that you need help with this question.

00:02 So it says, chris is planning to paint a house, i'm sorry, paint a building whose dimensions are shown below.

00:09 The front of the building has a door measuring 54 inches by 80.

00:16 The left and the right sides each have two windows measuring seven by four feet each.

00:22 So seven by four feet each.

00:25 This is the only thing in inches.

00:27 The back of the building has no window or door.

00:32 Use the given information.

00:33 So assuming the roof windows and door require no paint, what is the area in square feet that needs paint? so you're going to take, there's two 50, i'm sorry, not 50.

00:49 There's two 16 by nines plus two nine by forties.

00:56 So that's two times 16 times nine.

01:04 That's 144 plus two times 360.

01:14 So two times 144 is 288 plus two times 360 is 720.

01:26 And so then 1 ,008 feet cubed.

01:31 But then i have to take this number and i have to subtract the window in the four, the four windows in the one door.

01:39 So four times seven times four, that's four times 28.

01:46 Four times 28 is 112 feet squared.

01:55 That's not cubed, that's squared.

01:59 Let me erase this...
