That number is the ratio of 578,778,777 to 100,000,000 , so it's rational.
Here's a surprising factoid:
ANY number that you can completely write down on paper with digits...
and a decimal point or a fraction bar if you need them ... is rational.
If you can write it down ... without saying "repeating" or using symbols ...
it's rational.
        
             
        
        
        
The length of the diagonal and the shorter base are 17. 24 feet and 18. 7 feet long respectively. 
<h3>How to determine the length</h3>
The cosine rule is given as;

c = length of the diagonal
a = base length = 22 feet
b = 7 feet
