Answer: 4.4
Step-by-step explanation:
The formula for calculating the area of regular hexagon is given as :
Area = 

Where a is the length of a side.
Substituting the value given , we have :
50 = 

50 x 2 =

100 =

Divide through by 
= 
= 19.24500897
Take the square root of both sides :
a = 
a = 4.3869
To the nearest tenth
a = 4.4
Red Cards = 10
Other Cards (Black + Blue) = 10+20 = 30
So, the ratio would be: 10/30 = 1/3
So, your final answer is 1/3
