One side of a square is 10 units? which is greater the number of square unit for the area of the square or the number of units for the perimeter expain

If it is a square that means that all of the four sides are congruent, if that is so that means that all sides have a length of 10 units.

To calculate the perimeter you add up all of the sides so 10+10+10+10=40 units

To calculate are you multiply L by W so 10×10= 100

So the area is greater than the perimeter.
