Question

What is the perimeter of a square with side $6cm$?

Answer 1

Determine the perimeter of the square.

The length of the side of the square is $6\mathrm{cm}$.

Use the formula $P=4a$ to determine the perimeter:

$\begin{array}{rcl}P& =& 4\times 6\mathrm{cm}\\ \therefore P& \mathit{=}& 24\mathrm{cm}\end{array}$

Hence, the perimeter of the square is $24\mathrm{cm}$
