Question

zoes living room rug is 3 feet wide and 7 feet long she will cover the rug with 6 inch cardboard pieces for a painting project how many cardboard pieces will zoe need

Answer 1

Zoe will need 84 pieces if they are 6” by 6”

Answer 2

For this case we have that by definition, 1 foot equals 12 inches.

So:

`3 \ ft = 36 \ in\\7 \ ft = 84 \ in`

So, the area of the Zoes carpet is:

`A = 36 * 84 = 3024 \ in ^ 2`

If the cardboard pieces are
`6 \ in\ by\ 6 \ in`, then the area is:

`36 \ in ^ 2`

To indicate the number of necessary pieces we divide:

`\frac {3024} {36} = 84`

Thus, 84 pieces of cardboard are needed

Answer:

84
