Answer:
3.35 decimeter.
Step-by-step explanation:
We have been given that the first week, the plant's height measured 2.65 Decimeters. During the second week, Tania''s plant grew 0.7 Decimeter.
To find the height of Tania's plant at the end of second we will add 0.7 to 2.65.
[tex]\text{The length of Tania's plant at the end of 2nd week}=2.65+0.7[/tex]
[tex]\text{The length of Tania's plant at the end of 2nd week}=3.35[/tex]
Therefore, Tania's plant was 3.35 decimeter tall at the end of 2nd week
