Question

Please help, I have a few more lessons until I am done with my math course and I'd really like to finish.
Thank you so much.

You are given the job of laying carpet for a six-story building. At each floor the dimensions of the floor are 75 meters in length by 40 meters in width. A stairwell takes up a space 2.5 m by 1.5 m, and cuts through each floor. If the rest of the floor area is to be carpeted, how much carpeting will you need?

Total area is?

Answer 1

I'd suggest you think about just one floor at a time. We are told that the dimensions of the floor are 75 by 40 meters. What is the area of this one floor?

Answer 2

Hint: area = length * width

Answer 3

So when getting area you need to do length times width. If the length is 75 and width 45, then you multiply the two and get 3000. Are you just supposed to add 3000+3000 6 times since all 6 floors l=75 and w=45? Then subtract the extra space which is the stair case space? There's more than one way in which to do this problem. It seems easier and clearer to me to take the area of ONE floor (3000 square meters and then subtract the area lost to the stairwell opening. Then multiply the resulting difference by 6 and you'll be done.

Answer 4

75 m times 40 m comes to 3000 square meters.
2.5 m times 1.5 m comes to 3.75 sq. meters.

Subtract, please; write your answer here.
Then multiply that result by 6.

Answer 5

17,977.5 is what I got.

Answer 6

Cool. Not only have you solved this problem correctly, but also you have checked your work yourself. Way to go!!
