Answer:
100 feet in length
Step-by-step explanation:
Given the following question:
[tex]A=s^2[/tex]
In order to find the area of the square we have to multiply two of the lengths by itself.
[tex]A=s^2[/tex]
[tex]A=100^2[/tex]
[tex]A=100\times100[/tex]
[tex]100\times100=10000[/tex]
[tex]=10000ft^2[/tex]
Which means one side of the given square is "100 feet."
Hope this helps.
