You can put this solution on YOUR website! John wants to fence a 150 square meters rectangular field. He wants the length and width to be natural numbers {1,2,3,...}. What field dimensions will require the least amount of fencing?
.
You could create a "table":
width length area perimeter
1 150 150 302
2 75 150 154
3 50 150 106
5 30 150 70
6 25 150 62
10 15 150 50
15 10 150 50
25 6 150 62
30 5 150 70
.
From the above, we see that the answer is a field that is:
10 feet by 15 feet
