Surface area = area of 2 triangular sides + area of the roof + area of the base.
= 2 * 1/2 * 6 * 4 + 2 * 5*7 + 6 * 7
= 24 + 70 + 42
= 136 units^2
 
        
             
        
        
        
I think it’s the second choice
        
                    
             
        
        
        
The <u>answer would be 6</u>. The number line which shows you the number 6 or any solution for 6 would be your answer. 
 
        
             
        
        
        


Hence they are similar
#2
- <A=<H
- And ratio of sides are same
Hence both triangles are similar by SAS property
#3
