Answer:
The length of side of patio is 11.27 feet.
Option A is correct option.
Step-by-step explanation:
Area of patio = 127 ft^2
We need to find side length of the patio.
Since the patio is square, the formula used is:
[tex]Area\: of\: square = l^2[/tex]
where l is the side length of square.
Now, putting value of area we can find area of square.
[tex]Area\: of\: square = l^2\\127=l^2\\Switching\:sides\:\\l^2=127\\Taking\:square\:root\:on\:both\:sides\\\sqrt{l^2}=\sqrt{127} \\l=11.27[/tex]
So, the length of side of patio is 11.27 feet.
Option A is correct option.
