Question 975354: John wants to fence in a rectangular space in his backyard for his dog. He has 74 feet of fencing to surround the rectangular area. What should the dimensions of the region be if he wants the length to be 7 feet greater than the width? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! width=x
length=x+7
74=2x+2(x+7)
=4x+14
60=4x
x=15 feet
x+7=22 feet
perimeter is twice their sum, or 74 feet.
