Question

Roger wants to carpet a rectangular room with length of 8 3/4 feet and a width of 9 1/3 feet. If he has 85 square feet of carpet, how many square feet of carpet will be left after he covers the floor of the room?

Answer 1

12.66
`ft^2`

Explanation:

Given the dimensions of the room are
`8(3)/(4)`=
`(31)/(4)` and
`9(1)/(3)`=
`(28)/(3)`.

The area of the room =
`length*width`

Area=
`(31)/(4) *(28)/(3)`

Area=72.33
`ft^2`

The area of the carpet=85
`ft^2`

The area of carpet left= Total area of carpet - the area of the room

The area of carpet left= 85-72.33=12.66
`ft^2`
