Question 97031
Honestly, im not how to solve it correctly. But heres what i do have.
Go ahead and divide 104 by 4 (sides). You get 26
Since the legnth is 6 feet longer, just add 6 to the legnth and subtract 6 from the width, you end up with the legnth of both sides being 32, and the width of both sides being 20

Check:

Perimiter is adding the 4 sides together.
20+20=40
32+32=64
64+40=104
