The perimeter of the square is 4 4/5 dm. find the side length of the square.

All sides of the square are equal, the perimeter of the square is equal to the sum of the lengths of all sides. Let the side of the square be x, then the perimeter is x + x + x + x = 4x, on the other side, the perimeter is 4 whole 4/5 dm, that is, 24/5 dm, we make the equation 4x = 24/5;
x = (24/5) / 4;
x = (24/5) * 1/4;
x = 6/5;
x = 1 integer 1/5.
The side of the square is equal to 1 full 1/5 dm.
