We're saying
x*y=60
So
y = 60/x
Also
we're limiting x & y to integers
A graph will give an impression of the function we're dealing with.
.
| length | width | area |
| 1 | 60 | 60 |
| 2 | 30 | 60 |
| 3 | 20 | 60 |
| 4 | 15 | 60 |
| 5 | 12 | 60 |
| 6 | 10 | 60 |
| 10 | 6 | 60 |
| 12 | 5 | 60 |
| 15 | 4 | 60 |
| 20 | 3 | 60 |
| 30 | 2 | 60 |
| 60 | 1 | 60 |
