sq$\_$side$\_$len is read from input as an integer, representing the side length of a square. Compute the square's perimeter as sq$\_$side$\_$len$*4.$ Use an f$-$string with an $=$ after the expression in the replacement field so that both the expression and the result are printed.

Ex: If the input is:

$8$

then the output is:

sq$\_$side$\_$len$*4=32$
