Question

The perimater of the triangle is 30cm. its sides are in the ratios 1:3:2, then find its sides​

Answer 1

Answer:

1 * 5 = 5cm

3 * 5 = 15cm

2 * 5 = 10cm

Step-by-step explanation:

1+3+2 = 6

then do 30 / 6  = 5 to find one part of the ratio

1 * 5 = 5

3 * 5 = 15

2 * 5 = 10

Answer 2

Answer:  The lengths of the sides of the triangle are:

____________________________________

                     " 5 cm, 15 cm, and 10 cm " .

____________________________________

Step-by-step explanation:

____________________________________

1x + 3x + 2x = 30 ;  

In which the sides are:

1x ;  3x,  2x ;  

Find:  1x  ; 3x;  and 2x .

____________________________________

Let us begin by finding "x" :

____________________________________

1x + 3x + 2x = 30

1x + 3x + 2x = 6x ;  

→  6x  =   30  ;

Divide each side of the equation by:  " 6 " ;

     to isolate "x" on each side of the equation; and to solve for "x" ;

 →  6x / 6  = 30 / 6 ;

to get:

 →   x  =  5  ;

______________________________________

Now, solve for the length of each side;

______________________________________

 1x  =     x   =   5 cm ;

 3x =  (3*5) = 15 cm ;

 2x  =  (2*5) =  10 cm ;

______________________________________

Answer:  The lengths of the sides of the triangle are:

                     5 cm, 15 cm, and 10 cm .
