Answer:
A. 15
Step-by-step explanation:
Ooh, look! This triangle is a Pythagorean triple! Without even needing to use a formula, I can tell that you are correct and the answer is A. 15.
It's based off of a 3-4-5 right triangle, because 9-12-15 simplifies to that if you divide every term by 3. It's basically just a bigger version of a 3-4-5 triangle! Isn't math cool:)
 
        
                    
             
        
        
        
In the drawing the base picture shows two squares on next to each other
The side picture shows three squares, one next to other and one above the square that right most.
 The front picture shows two one square above other square.
The three dimensional figure that corresponds to those three view is a set of three boxes two in the base and one above one of the boxes of the base.

Answer:
Step-by-step explanation:
lets have one side =a
P=3a+a+(17+a)=52

a=7
second side=21
third side=24
