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

The area of a rectangle is length times width. For one room, length = 20.5 ft, width = 14 ft. So area of one room is $14\times20.5 = 287$ square feet.

Step2: Calculate total area of four rooms

Since there are four identical rooms, total area is $4\times287 = 1148$ square feet.

Step3: Calculate number of carpet rolls needed

Each roll covers 200 square feet. So number of rolls is $\frac{1148}{200}= 5.74$. Since we can't buy a fraction of a roll, we need to round up to the next whole number.

Answer:
