1) 2 + 4 + 6 + . . . + 2n=n(n+1)

Atriangle with all sides of equal length is a/an triangle. a. right b. scalene c. equilateral d. isosceles

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?
