Answer:
A)
and 
B) w=8 l=28
C) w=11 l=39 does not work
Step-by-step explanation:
An inequality is an equation that has a solution set or many possibilities for solutions. You write it with an inequality sign like
.
A) The width must be at least 10 which means it must be equal o 10 or greater.

The perimeter has the formula for a rectangle of 2l+2w=P. If the perimeter is no more than 72, then it is equal to 72 or less than it.

B) The width could be 8 and the length could be 28 since 2*8+2*28 = 72
C) The width cannot be 11 and the length 39 cince 2*11 + 2*29 = 100.
