Answer :
Given Data:
The perimeater of the square is: p=16
Let 'a' be the length of one side of the given square.
The expression to calculate the perimeter of a square is,
[tex]P=4a[/tex]Substitute values in the above expression, and solve for 'a'.
[tex]\begin{gathered} 16=4\times a \\ 4a=16 \\ a=\frac{16}{4} \\ a=4 \end{gathered}[/tex]Thus, the lenth of one side of the square is 4 units.
