For this case we must find the current height of Osian. For this, we use the following rule of three:
1.5 m ----------------> 100%
x -----------------------> 120%
From here, we clear the value of x.
We have then:
[tex]x = \frac {120} {100} (1.5)\\x = 1.8 m[/tex]
Answer:
The current height of Osian is given by:
[tex]x = 1.8 m[/tex]
