The side length cannot be negative, hence the side length of the patio will be 10 feet
Give the expression that represents the statement given as:
[tex](s+4)^2 = 196[/tex]
We need to get the length of the side of the patio "s"
[tex](s+4)^2 = 196\\s+4 = \pm\sqrt{196}\\s+4=\pm14[/tex]
Subtract 4 from both sides
[tex]s+4-4=14-4\\s=14-4\\s =10ft[/tex]
Since the side length cannot be negative, hence the side length of the patio will be 10 feet
