Please answer quick it’s not a big question people say it’s easy but not for me so please answer

Figure abcd is a parallelogram. if point c lies on the line x = 2, what is the y-value of point c

For what value of x does 4x = (1/8) x + 5?

When solving this problem: 3025/5.5 = a/90.75 you get 49912.5 which would be the length of one of the sides of a square when the area is only 90.75 inches. is that answer correct, why, and how is it possible?
