The perimeter of a rectangular yard is completely surrounded by a fence that measures 14 meters. What is the length of the yard if the area of the yard is 6 meters squared?  Choose the correct choice from the following options:  A) 8  B) 6  C) 2  D) 4  E) 3
Perimeter of rectangular yard = 2(l + b) = 14 --&gt; l + b = 7   Area = l * b = 6   b = 7 - l   l(7 - l) = 6   7l - l^2 = 6   l^2 - 7l + 6 = 0   Upon simplifying we get l = 1 or 6. Only 6 is there in the answer choice.   Answer: 6
