we know that having similar triangles so the ratio of sides,area and volume are same.

we know that  will be the area of triangle.
 will be the area of triangle.

so 
so the ratio of the perimeter of two triangles will be 

ratio of the perimeter=
 
        
                    
             
        
        
        
In solving for the value of x in the equation 1331x^3 - 216 = 0, the steps are shown below:
1331x^3 - 216 = 0
(1331x^3 = 216) / 1331
x^3 = 216/1331
x = cube root (216/1331)
x = 6/11
Therefore, the value of x in the equation is 6/11.

Answer:
3.5
Step-by-step explanation:
These are similar triangles.
BC:AC = BD:AD
6:5  is the ratio.
Then, simply multiply:
4.2 x 5/6 = 3.5
So, x = 3.5!
