Answer: Option B.
Step-by-step explanation:
The perimeter of a square is equal to 4 times the lenght of one side.
For this we can calculate the difference between two of the vertices.
The vertex Z is at (0, 5) and the one in W is at (-4,0)
Then the difference is equal to:
Z - W = (0, 5) - (-4, 0) = (4, 5)
We can calculate the lenght of this vector as:
L = √(4^2 + 5^2) = √(16 + 25) = √41 = 6.4 units.
then the perimeter is 4*6.4 units = 25.6 units
The correct option is B.
