For a square,
[tex] A = s^2 [/tex]
[tex] s^2 = A [/tex]
[tex] s^2 = 224 ~sq ~ft [/tex]
[tex] s = \sqrt{224~sq~ft} [/tex]
[tex] s = \sqrt{16 \times 14}~ft [/tex]
[tex] s = 4\sqrt{14}~ft [/tex]
The exact length of each side is [tex] 4 \sqrt{14}~ft [/tex] which is 14.97 ft rounded off to the nearest hundredth.
