Answer :
First, subtract the height he will grow to to the height he is now.
132 - 90 = 42
Now divide this from 3.5.
42 / 3.5 = 12
So it will take 12 months for him to grow to a height of 132 cm.
132 - 90 = 42
Now divide this from 3.5.
42 / 3.5 = 12
So it will take 12 months for him to grow to a height of 132 cm.
