Answer:
4.24
Step-by-step explanation:
Since it is the midpoint, it means that the entire diagonal will measure twice, that is 3 * 2 = 6
To calculate the length of the sides, we can do it by means of Pythagoras, since it is a square a = b
c ^ 2 = a ^ 2 + b ^ 2
c ^ 2 = 2 * a ^ 2
6 ^ 2 = 2 * a ^ 2
a ^ 2 = 36/2
a = 4.24
therefore, it means that the sides of the square measure 4.24
