Given:
The initial length of a tree = 34''
The tree grows 7.5'' every year.
To find:
The height of the tree in 5 years.
Solution:
It is given that,
Length of tree increased each year = 7.5''
Length of tree increased 5 year = 5×7.5''
= 37.5''
The initial length of a tree is 34''. So, the length of tree after 5 years is
34'' + 37.5'' = 71.5''
Therefore, the length of the tree in 5 years is 71.5''.
