The area of a rectangle is 12 square feet. What are all the possible integer values of its perimeter?
I got:
1. all sides equal to 3
2. 5, 5, 1, 1
3. 4,4,2,2
Did I miss any combinations?
the integer dimensions must be factors of 12. So,
1x12
2x6
3x4
You worked out the combinations for a perimeter of 12.
Using the above dimensions, now you can work out the possible perimeters
