The side of the square is 4 cm since 4x4= 16
All you will have to do is put this inside of a graph and then see if it goes through the origin.
Let the number of comic books be X
if we add 14 to X = 24
so we will find the value of X to get half initial number of comic books William had.
14+X=24
X=24-14
X=10
so the total innitial number of comic books William had is 10+10=20 books.
