We know there are no squares between 100² and 101².

So we just want to know how many numbers between a and b exclusive, which is

n = b - a - 1

For example between 10 and 20 exclusive we get n=20-10-1=9, which is right.

For our problem here we can factor using the difference of two squares and get:

n = 101² - 100² - 1 = (101 - 100)(101 + 100) - 1 = 1(201) - 1 = 200

d. 200

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
