Question

two equal side of a triangle are each side four meter less than three time the third side if the perimeter of the triangle is fifty five meter find the length of side​

Answer 1

Answer:

Step-by-step explanation:

Given :

two equal side of a triangle are each side four meter less than three time the third side if the perimeter of the triangle is fifty five meter find the length of side

To find :

the perimeter of the triangle is fifty five meter find the length of side​

Solution :

1st side 2nd side =3x-4

x+3x-4+3x-4=55

7x=55+4+4

7x=63

x=9

1st side =3x9-4-23m 2nd side =23m

3rd side 9m

Answer 2

Answer:

$\huge\mathfrak\blue{Answer}$

Step-by-step explanation:

Solution

Let x be the third side,

Then (3x−4) will be length of the equal sides.

As per the question-

55=x+2(3x−4)

55=x+6x−8

55=7x−8

55+8=7x

63=7x

9=x

Therefore, the third side = x=9m.

Therefore, the third side = x=9m.Hence, the equal two sides = (3x−4)=(3×9−4)=27−4=23m each.

Hope it helps you
