Answer: 
Step-by-step explanation:
Given
The perimeter of one equilateral triangle is P
The lengths of the equilateral triangle are equal 
Suppose x is the length of each side

i.e.

 
        
             
        
        
        
Yes, we apply the distributive property to simplify this expression.
3*5 = 15
6*3 = 18
15 + 18 is the final answer.

There would be 35 rulers. 
In order to solve this, use cross multiplication. 
6/10 = 21/x -----> cross multiply
10*21 = 6*x
210 = 6x 
35 = x
