Answer 1

`\begin{gathered} \text{The length of the football is 300 ft long} \\ \text{The width is 160 ft wide} \\ The\text{ shape of a field is rectangular in shape} \\ \text{Area of a rectangle = Length X width} \\ \text{Area of a rectangle = 300 x 160} \\ \text{Area = 48,000 ft}^2 \\ \text{Convert ft}^2\text{ to acres} \\ 1ft^2-------2.296x10^(-5)\text{ acres} \\ 48,000ft^2\text{ ------- x acres} \\ \text{Cross multiply} \\ x\cdot1=48,000\cdot2.296\cdot10^(-5) \\ x\text{ = 4.8 }\cdot10^4\text{ x 2.296 }\cdot10^(-5) \\ x\text{ = 4.48 x 2.296 }\cdot10^{4\text{ -5}} \\ x\text{ = 11.0208 x 0.1} \\ x\text{ = 1.10 acres} \\ \text{The answer is 1.10 acres} \end{gathered}`
