A postal service says that a rectangular package can have a maximum combined length and girth of 108 inches. The girth of a package is the distance around the perimeter of a face that does not include the length.

a. Identify an inequality that represents the allowable dimensions for the package.

2w+2h≤108
2w+2h≤108

2w+2h>108
2w+2h>108

2w+2h<108
2w+2h<108

2w+2h≥108
2w+2h≥108

l+2w+2h≤108
l+2w+2h≤108

l+2w+2h≥108
l+2w+2h≥108

l+2w+2h<108
l+2w+2h<108

l+2w+2h>108
l+2w+2h>108
Question 2
b. Choose three sets of dimensions that are reasonable for the package.

l=12, w=5, h=5
l=12, w=5, h=5

l=19, w=35, h=10
l=19, w=35, h=10

l=20, w=8, h=12
l=20, w=8, h=12

l=30, w=20, h=19
l=30, w=20, h=19
