Question

Each of the two equal sides of a triangle is four meters less than three times the third side. Find the sides of the triangle, if it’s perimeter is 55 meters?

Answer 1

Answer:

let 3rd side=x

1st side =2nd side =3x-4

ATQ

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

7x=55+4+4

7x=63

x=9

1st side =3×9-4=23m

2nd side =23m

3rd side =9m
