For the perimeter of a rectangle, the formula is;
[tex]\text{Per}=2(l+w)[/tex]
In this instance, the perimeter is 306 yards while the width is 59 yards. Substituting the given values we would have;
[tex]\begin{gathered} 306=2(l+59) \\ 306=2l+118 \\ \text{Subtract 118 from both sides;} \\ 188=2l \\ We\text{ now divide both sides by 2} \\ \frac{188}{2}=\frac{2l}{2} \\ 94=l \end{gathered}[/tex]
ANSWER:
The length of the rectangular field is 94 yards
