Question

Angela is carpeting a rectangular conference room that measures 20

feet by 30 feet. If carpet comes in rectangular pieces that measures 5 feet
by 4 feet, how many pieces will she need to carpet the entire room?

Answer 1

`a = lw`

`a = (30)(20)`

`a = 600 \: {ft}^(2)`

The conference room has an area of 600 ft²

//

`a = lw`

`a = (5)(4)`

`a = 20 \: {ft}^(2)`

The carpet has an area of 20 ft²

//

`(600)/(20) = 30`

She would need 30 pieces to carpet the entire room.
