Answer:
33 inches
Step-by-step explanation:
This is just a very simple geometry question.
Area is length x width.
So first, we have to find the width, which is 54/12=4.5.
Perimeter is all four sides added together.
We know opposite sides in a rectangle are congruent, so 2 sides would be 12 and 2 would be 4.5.
If we add them all together, it would be 9+9+4.5+4.5=33.
