(I'm a Mac user so I asked Siri.) hence 1 1/3 of an acre is \[\frac{4}{3} \times 43,560 = 58,080 \mbox{ square feet.}\] If the shape of this region is a square with side length $L$ feet then its area is \[L^2 = 58,080 \mbox{ and thus } L = \sqrt{58,080} = 241 \mbox{ feet.}\] If the region is a rectangle of length $L$ feet and width $W$ feet the you know that $L \times W = 58,080$ square feet. There are many values of $L$ and $R$ that will give $L \times W = 58,080.$ For example $L$ could twice $R,$ or three times $R,$ or one and a half times $R.$ I hope this helps,
