Answer:
Actual Height = 27.11 m
Step-by-step explanation:
Given:
Height of model rocket = 4.5 % of actual Height
Model Height = 1.22 m
To Find:
Actual Height of rocket = ?
Solution:
We have to Find the Actual Height of the rocket
Let actual height be x
Now it is given that
Height of model rocket = 4.5 % of actual Height
As we have the values so putting it in it becomes
1.22 = 4.5 % * x
it could be written as

Multiplying both sides by 
it becomes
1.22*
= x
= x
27.11 m =x
or
Actual Height = 27.11 m
