Question 1194846
<font color=black size=3>
36000 square feet of grass = 1 gallon of gas
3.6*36000 square feet of grass = 3.6*1 gallons of gas
129,600 square feet of grass = 3.6 gallons of gas


I multiplied both sides by 3.6 in the second step.


If we assume the lawn is a square, then the side length is  {{{sqrt(129600) = 360}}} feet. Meaning that the max length of the square lawn is 360 feet. 


If the lawn is some other shape, then we simply don't have enough information to answer the question.
