Rachel needs several rows of rectangle-shaped shingle for her new roof
The length of each shingle is 5/6 feet
Length of the roof is 70 feet
The number of shingles she needs for a row is
[tex]\begin{gathered} \text{Number of shingles for a row}=\frac{length\text{ of the side of roof}}{length\text{ of the shingle}} \\ \text{Where }length\text{ of the shingle}=\frac{5}{6}ft \\ length\text{ of the side of roof}=70ft \\ \text{Number of shingles for a row}=\frac{70}{\frac{5}{6}}=\frac{70\times6}{5}=84\text{ shingles} \end{gathered}[/tex]
Hence, the number of shingles she will need for a row is 84
