Question

Two equal sides of a triangle are each 5 meters less than twice the third side.if the perimeter of the triangle is 55m find the length of two sides

Answer 1

2x-5+2x-5+x =55
5x=65
x=13. third side

2x-5=21m ans

Answer 2

♠ ANSWER :

❇ ACCORDING TO THE QUESTION,

Let two equal sides be x m each.
And third side be y.

Then, x = 2y - 5. [ First side ]

x = 2 y - 5. [ Second side]

Perimeter of triangle = 55 m.

Perimeter of triangle = x + x + y. [ Sum of length of all three sides. ]

2y - 5 + 2 y - 5 + y = 55

4 y - 10 + y = 55

5 y = 55 + 10

y = 65 / 5

y = 13 m.

⏺️First side = 2y - 5

2 ( 13 ) - 5 = 26 - 5 = 21 m.

⏺️Second side = 21 m.

⏺️Third side = 13 m.
