You can't!
Here's why:
The perimeter, P, of a rectangle with length, L, and width, W, is given by:
P+=+2%28L%2BW%29 Now if P+=+60, then:
60+=+2%28L%2BW%29 Divide both sides by 2.
30+=+L%2BW
Now what two numbers added together will give 30?
Try...
1+29 = 30
2+28 = 30
3+27 = 30
4+26 = 30
5+25 = 30
6+24 = 30
7+23 = 30
