Question 208018: Jarod is having a problem with rabbits getting into his vegetable garden, so he decides to fence it in. The length of the garden is 7 feet more than 5 times the width. He needs 86 feet of fencing to do the job. How many feet is the length of the garden?
Answer by rapaljer(4671) (Show Source): You can put this solution on YOUR website!
Let x = width of the garden
5x+7 = length of the garden
2W + 2L = P
2(x) + 2(5x+7) = 86
2x+10x + 14 = 86
12x + 14= 86
12x=72
x=72/12=6 feet WIDTH
LENGTH = 5x+7
LENGTH = 5*6+ 7 = 30 +7 = 37 feet
Check:
2*6 + 2*37
12 + 74 = 86 feet
