Answer:
8.68 seconds
Step-by-step explanation:
Given:
Height of the deck above the street, s = 370 m
Since the condition is of free falling 
thus, 
initial speed, u = 0
Acceleration of the penny = acceleration due to gravity, g = 9.81 m/s²
Now, 
from Newton's equation of motion, we have

here, 
s is the distance
a is the acceleration
t is the time
on substituting the values, we get

or
t² = 75.433 
or
t = 8.68 seconds
 
        
             
        
        
        
123/0.75 =164
the answer is 164
        
                    
             
        
        
        
Here you go :) have a good day
 
        
        
        
The length of the rectangle would be 21 
Proportion to set it up would be 7/3 x X/9 cross multiply and solve for x which is 21
