The position of A is located at : -3.75 explanation:
We know this because half of -3 and -4 it would be 50 but this is more than half way so if you count 25 cents more on a quarter it would be 75cents
289 square root = 17
17*17=289
Say 17 was length and 17 was width. L*w=289
Also, all sides of the square are the same.
