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]
