The expression that represents the perimeter of a square is the sum of all its sides (length+length+width+width)
Because this is a square, all the sides are equal, so we can save ourselves the trouble of adding all the sides, and simply multiply the expression 4.8x +2.4 by 4.
Thus, the expression that represents the perimeter of this square is 4(4.8x +2.4)
Enjoy your evening :)
