Problema Solution
cindy has 42 meters of fencing. She plans to fence a rectangular dog run that is 6 meters wide. How long can the run be made?
Answer provided by our tutors
Let 'x' represent the length of the run.
Since the perimeter of a rectangular run with dimensions x and 6 is:
P = 2x + 2*6
P = 2x + 12
and we also know that Cindy has 42 meters of fencing we can write:
2x + 12 <= 42

x <= 15 ft
The run can be maximum 15 feet long.
