Answer:
4 2/3  cm
Step-by-step explanation:
When we have area, it is the related to the scale factor by the scale factor squared
Area large/ area of small = 49/9
Take the square root 
sqrt(49/9)  = 7/3
The scale factor is 7/3    large to small
The small side is 2 cm
large         7            x cm
--------   =  ------ =  -----------
small           3           2 cm
Using cross products
7*2 = 3x
Divide by 3
14/3 = 3x/3
14/3 = the large side
4 2/3  cm
