Figure is missing here so giving u general Solution

Let say ABC is triangle

& D is the Blue Dot

now we have to enlarge the triangle by sclae factor 3

A'B'C'

First we major the  A , B  & C  from D

in the graph  

we will check  how many   (left / right) , (up/down) is A from D

then we will multiply the (left / right) , (up/down) by 3

and we fil find point A'   from D by counting  (left / right) , (up/down)

Similarly we will do to get B'  & C'

and then we will join A'B' , A'C' & B'C'

This Way we will get the triangle scale factor 3 , where Blue dot will be at the center of enlargement
