# A square has an area of 196 cm2, what is the perimeter of the square?

Sep 19, 2015

Area of square is x^2 and ${x}^{2} = 196 c {m}^{2}$
=>$x = 14 c m$
$p e r i m e t e r = 4 x = 4 \cdot 14 c m = 56 c m$

The perimeter of the square is $56 c m$

#### Explanation:

With an area of $196 c {m}^{2}$, the length of each side of the square is $\sqrt{196} c m = 14 c m$. The perimeter of a square is $4$ times the length of the side: $4 \cdot 14 c m = 56 c m$
