Answer:
28
Step-by-step explanation:
Area of a square =
[tex]s^2[/tex]
Perimeter =
[tex]4\times s[/tex]
Where s = side
Solve for s using the area
[tex]A =49\\\\49 = s^2\\\\Square\:root \:both\:sides\:of\:the\:equation\\\\\sqrt{49} = \sqrt{s^2} \\\\7 =s\\\\s =7[/tex]
Find the perimeter
[tex]4\times s\\\\= 4 \times 7\\\\= 28[/tex]
