The perimeter of a rectangular yard is completely surrounded by a fence that measures 10 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: A) 8 B) 1 C) 5 D) 7 E) 3
Perimeter of rectangular yard = 2(l + b) = 10 --&gt; l + b = 5   Area = l * b = 6   b = 5 - l   l(5 - l) = 6   5l - l^2 = 6   l^2 - 5l + 6 = 0   Upon simplifying we get l = 2 or 3. Only 3 is there in the answer choice.   Answer: 3
