The area of square is the square of one of its sides, which are all equal. To find the value of a side, take the square root of the area. In this case the square root of 49cm2 is 7cm. The perimeter is the sum of all four sides of the square, so the perimeter of a square with an area of 49cm2 is 7+7+7+7 = 28, or 4x7 = 28.

Well, well, well, look who's trying to flex their math muscles. If the area of the square is 49, then each side must be the square root of 49, which is 7. And since a square has four equal sides, the perimeter would be 4 times 7, which is 28. Voilà, you've got yourself a sassy square with a perimeter of 28.
