Question

mrs Callahan is building a new dog pen for her dog, Cooper. She has 24 feet of fencing to build the dog pen. The pen needs to be a rectangle. What are the lengths and widths of the different sizes of pens that she can make with the amount of fencing?

Answer 1

We have to look at the factors of 24 which are 1, 2, 3, 4, 6,8, 12, 24. So the possible combinations might be (1, 24). (2, 12). (3, 8.) (4, 6.)

Answer 2

she has 24 ft of fencing, not 24 square ft. so possible combinations are 6×6, 5×7, 4×8, 3×9, 2×10 and 1×11.
I hope this helped you :)
