add first the heights

  1.08 m
+ 1.4 m
+ 1.26 m
+ 1.32 m
+ 1.48 m
-----------------
=6.54 m

divide the sum by the no. of values. the number is 5, since there are 5 heights needed to be averaged

6.54 m
-------------
5

=1.308 or 1.31 m is the average height

First Method
Formula (In Phrase)

Add all the values, then the sum will be divided into how many values you have added overall.

Formula (Algebraic Expression)
(v + v) / nv
Wherein 
v = value
nv = no. of values

   1.08 (1st v.)
   1.40 (2nd v.)
   1.26 (3rd v.)
   1.32 (4th v.)
+ 1.48 (5th v.)
   6.54 ÷ 5 = 1.308

So, rounding off, the answer is 1.308 when rounded is 1.3
