It should be the second one
Namely, what is 11.65 in percentage from 24.9
if we take 24.9 to be the 100%, let's see

solve for "x".
Let side B = X
Then side A = 2x
Side C = 2x +1
Mow you have x + 2x + 2x+1 = 76
Simplify:
5x +1 = 76
Subtract 1 from both sides:
5x = 75
divide both sides by 5:
x = 75 /5
x = 15
Side A = 2x = 2*15 = 30 cm
Side B = x = 15 cm
Side C = 2x +1 = 2*15 +1 = 30+1 = 31 cm
The remainder is 3.
You can get this by performing long division to answer the question. Since there is a remainder, it is not a factor.
