Write a system of inequalities that describes the possible solutions to the problem.Andy decides to fence off a rectangular piece of his land to use as a vegetable garden. He has 80 feet of fencing so the perimeter of the fenced in area cannot exceed 80 feet. The length of the garden is to be at least 4 feet longer than the width. The width must be at least 6 feet. Write a system of inequalities that describe this situation. Let w represent the width and l represent the length.

A. l + w ? 80 
l ? w + 4 
w ? 6
B. l + w ? 80 
w ? l + 4 
l ? 6
C. 2l + 2w ? 80 
l ? w + 4 
w ? 6
D. 2l + 2w ? 80 
w ? l + 4 
l ? 6
