Answer:
The dog is 20 inches tall now.
Step-by-step explanation:
Given that:
Height of dog when it was a puppy = [tex]5\frac{1}{2}[/tex] inches
Height of dos now = [tex]14\frac{1}{2}[/tex] than previous height
It means that we will add this height in the height of dog when it was a puppy.
Height of dog now = [tex]5\frac{1}{2}+14\frac{1}{2}[/tex]
Height of dog = [tex]\frac{11}{2}+\frac{29}{2}=\frac{11+29}{2}=\frac{40}{2}[/tex]
Height of dog = 20 inches
Hence,
The dog is 20 inches tall now.
