Respuesta :
C. 17 ft.
a rectangle's area is Length • Width
since it is a square we know that Length = Width, therefore, Area = Length • Length or Area = Length^2.
[tex]290 = {x}^{2} [/tex]
[tex] \sqrt{290 } = x[/tex]
[tex]17 = x[/tex]
you just do the inverse operation to find the side Length of the square.

Answer:
C. about 17 feet
Step-by-step explanation:
Since, we know that,
The area of a square is,
[tex]A=s^2[/tex]
Where,
s = side length,
If A = 290 square feet,
[tex]\implies 290 = s^2[/tex]
[tex]\implies s = \sqrt{290}=17.0294\approx 17[/tex]
Hence, the side length of the patio would be about 17 ft,
OPTION C is correct.
