Answer 1

10 bundles

Explanation:

We have that the area can be calculated by multiplying both sides (length and width) , like this:

`\begin{gathered} L=18\text{ ft} \\ W=10\text{ ft 6 in} \\ 1\text{ ft is 12 in} \\ \text{ therefore:} \\ W=10ft+6in\cdot\frac{1\text{ ft}}{12\text{ in}}=10ft+0.5ft=10.5\text{ ft} \\ \\ \text{Floor area:} \\ A=L\cdot W=18\cdot10.5 \\ A=189ft^2 \end{gathered}`

Since each strip is 23 ft² to calculate how many strip will be used we need to divide the area of the whole floor by the area of each strip. Therefore:

`\text{ number of strips =}(189)/(23)=8.22`

Although there must be 20% more strips, we must multiply that value by 1.20, therefore:

`\text{ number of strips }=8.22\cdot1.2=9.86\cong10`

It will take 10 bundles of strip flooring to cover the rectangular floor
