Answer: There are 12 pieces of 6 foot square paper needed to wrap.
Step-by-step explanation:
Since we have given that
Length of piece of wrapping paper = 6 square foot
Length of paper each present needs is given by
[tex]3\frac{1}{8}\text{ square feet}[/tex]
Number of presents he wants to wrap = 2
Total length of wrapping paper she needs is given by
[tex]2\times \frac{25}{8}\\\\=\frac{25}{4}[/tex]
We'll use the unitary method,
[tex]\text{For }\frac{25}{8}\text{ square feet present it needs wrapping paper of length }=6\\\\[/tex]
[tex]\text{For }1 }\text{ square feet present it needs wrapping paper of length is given by}\\\\[/tex]
[tex]\frac{6}{\frac{25}{8}}\\=\frac{48}{25}[/tex]
[tex]\text{For }\frac{25}{4} \text{ square feet present it needs wrapping paper of length is given by}\\\\[/tex]
[tex]\frac{48}{25}\times \frac{25}{4}=12[/tex]
∴ there are 12 pieces of 6 foot square paper needed to wrap.
