Answer 2

$\fontsize{18}{10}{\textup{\textbf{The perimeter of square is 112 cm.}}}$

Step-by-step explanation:

Let the length of a side of the equilateral triangle and the square be l and L respectively.

Then, according to the given information, we have

$\textup{Perimeter of equilateral triangle}=42\\\\\Rightarrow l+l+l=42\\\\\Rightarrow 3l=42\\\\\Rightarrow l=14.$

So, the length of a side of the square will be

$L=2\times l=2\times14=28.$

Therefore, the perimeter of the square is given by

$P_s=4L=4\times28=112.$

Thus, the required perimeter of the square is 112 cm.
