Question

Shae is covering 3 walls in her bedroom with wallpaper .The measurement of each wall is 12ft x14 ft a roll of wallpaper covers 42 square feet . How many rolls should Shae purchase

Answer 1

1 wall is 12x14 so that's 168 square feet
it's 3 walls so 3x168 is 504
each thing of wallpaper covers 42 square feet so divide 504 by 42 (and if you have a fraction/remainder, round up)
504/42 is 12 though so you don't need to round, the answer is just 12

Answer 2

Answer:

12

Step-by-step explanation:

3 walls

its takes 4 rolls to paint one wall or

12 x 14 = 168 1 roll = 42 so

42 - 168

42 - 126

42 - 84

42 - 42 = 0

4 rolls = 1 wall

4 x 3 = 12
