The width of the rectangle is 71 m
Mathematically, the area of a rectangle can be calculated using the formula;
[tex]\begin{gathered} \text{Area = length }\times\text{ width} \\ \\ 6035\text{ = 85 }\times\text{ width} \\ \\ \text{width = }\frac{6035}{85} \\ \\ \text{width = 71 m} \end{gathered}[/tex]
