Question 8

The area of a rectangular floor (in square centimetres) is calculated using the following formula:

\text{area (in cm}^2\text{)} = \text{length} \times \text{width}

To convert this area to square metres ( $m2\text{m}^2$ ), the area in $cm2\text{cm}^2$ is divided by $00010\,000$ .

The total cost of carpeting is then found by multiplying this area in $m2\text{m}^2$ by the price per square metre.

The algorithm below is designed to output the total carpet cost for a room with a length of 500 cm, a width of 400 cm, and a carpet price of £25 per square metre.

A subroutine called calcCarpetCost has been developed as part of the algorithm.

Complete the program by identifying the correct term from the pool of options to fill each of the six empty gaps.
