Question

jim wants to put carpet in four identical rooms. each room is 14 ft by 20.5 ft. a roll of carpet will cover 200 ft². how many rolls will he need?

Explanation:

Step1: Calculate area of one room

Area of a rectangle is length × width. So for one room, area = $14 \times 20.5$ = $287$ $ft^2$.

Step2: Calculate total area of four rooms

Total area = $4 \times 287$ = $1148$ $ft^2$.

Step3: Calculate number of carpet rolls needed

Divide total area by area per roll: $\frac{1148}{200}$ = $5.74$. Since we can't buy a fraction of a roll, we round up to the next whole number.
