Depends on the shape we are talking here. I believe you are taking about a square, so: The equation for area for a square is: s^2, s representing the length of 1 of the squares sides (a square is even all the way around, so 1 side is the same as all) 8^2=64, so I can assume this is a square by this. Knowing it's a square, and that one of the sides is equal to 8, and the other 3 sides are the same length, I can do 8*4, which equals 24. The perimeter is 24
Fraction adding: Okay, so if you have two fractions with the same denominator like 2/3 and 1/3 then they are easily added. Just add the numerators together and then keep the denominator. Like this: 2/3 + 1/3 = 3/3 or 1 whole. Here is something for fractions with unlike denominators.
