Robert wants to install windows in a bus barn to improve the airflow in the summer month. If Robert makes his own screens, he can save money. To have screen material to fold over the window frame, Robert needs to cut 5 1/2 foot by 5 1/2 foot squares. The black wall by the offices requires four windows. For a good cross-flow of air, Robert will build five windows on each of the other two walls of the barn. How many square inches of screen will be needed for all the windows? 423.5 sq in. 5082 sq in. 39,204 sq in. Not here

Alright, let's work through this together slowly, because I'm still not grasping this concept Let's first find the area of one of the squares he plans to cut. Do you know how to find an area of the square?
anonymous
  • anonymous
Um... Yes... I think....
FortyTheRapper
  • FortyTheRapper
Ok, I understand the problem now. What do you find the area to be?
anonymous
  • anonymous
I do not know... I don't understand this....
FortyTheRapper
  • FortyTheRapper
So they give us that he needs to make squares that are 5 1/2 by 5 1/2.. which also means 5.5 by 5.5 Is the area of a square = one side * one side, what would that be?
anonymous
  • anonymous
5.5 times 5.5 ?
FortyTheRapper
  • FortyTheRapper
Right!
FortyTheRapper
  • FortyTheRapper
What would that equal?
anonymous
  • anonymous
Thank you for helping me. :)
FortyTheRapper
  • FortyTheRapper
No problem! You got it from here?
anonymous
  • anonymous
30.25

Sorry I'm a bit slow... And I will still need your help
FortyTheRapper

Right! So we got the area of one square He says the back window must have 4 and two of the sides must have 5 each, so how many is that in total?
anonymous
  • anonymous
So we do 5.5 times 4 ?
FortyTheRapper
  • FortyTheRapper
Yes, you can do it that way I recommend to add all of the sides together first to make it easier though. If the back has 4, one side has 5, and the other has 5, how many is that in total?
anonymous
  • anonymous
So I add 4 + 5 + 5 ?
FortyTheRapper
  • FortyTheRapper
Correct!
anonymous
  • anonymous
Oh okay. I got 14.
FortyTheRapper
  • FortyTheRapper
Right, so now we got 14 squares We also know that the area of 1 square is 30.25 What would you do to get the answer (To find the area of 14 squares)?
anonymous
  • anonymous
we multiply ?
FortyTheRapper
  • FortyTheRapper
Yes!
anonymous
  • anonymous
Oh okay. :)
anonymous
  • anonymous
423.5
FortyTheRapper
  • FortyTheRapper
Yep, and you should get one of those answer choices
FortyTheRapper
  • FortyTheRapper
Right!
anonymous
  • anonymous
Oh thank you so much for helping me !! :)
