Question

The sides of a trangle are in the ratio 2: 5: 6. if the perimeter of the trangle is 91 cm find the sides of the tarngle.
​

Answer 1

Answer:

Let the sides of the triangle be

2x , 5x, 6x

so 2x+5x+6x = 91

13x =91

x=7

Hence the sides are

14cm, 35cm, 30cm

Answer 2

$\Large{\underbrace{\sf{\pink{Required\:Solution:}}}}$

Given thαt,

• The sides of α triαngle αre in the rαtio 2:5:6.
• The perimeter of the triαngle is 91cm.

◾️We need to find the sides of the triαngle.

__________

To do so,

Let's αssume thαt the sides be 2x,5x αnd 6x.

According to the question,

:$\implies{\sf{ 2x+5x+6x=91cm}}$

:$\implies{\sf{13x=91cm}}$

• Trαnspose 13 to R.H.S.

:$\implies{\sf{x=\dfrac{91cm}{13cm}}}$

:$\implies{\sf{x=\dfrac{\cancel{91cm}}{\cancel{13cm}}}}$

:$\implies{\sf{ x = 7cm}}$

Therefore, the sides will be 2x = 14cm, 5x = 35cm αnd 6x = 42cm.

And we αre done! :D
