Question

What’s.the perimeter of a square with an area of 49 cm2

Answer 1

28

Explanation:

Area of a square =

`s^2`

Perimeter =

`4* s`

Where s = side

Solve for s using the area

`A =49\\\\49 = s^2\\\\Square\:root \:both\:sides\:of\:the\:equation\\\\√(49) = √(s^2) \\\\7 =s\\\\s =7`

Find the perimeter

`4* s\\\\= 4 * 7\\\\= 28`
