Answer 2

Correct Question :-

Each of the two equal sides of a triangle are 4 m less than three times the third side.

Find the dimensions of the triangle, if its Perimeter is 55 m.

Answer :-

Let 3rd side be x

According to the Question ,

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

x + 3x - 4+ 3x-4

↪55

7x = 55 + 4 + 4

7x = 63

$\large \:x = \frac{63}{7}$

↪x = 9

↪1st side =3 × 9 - 4 = 23 m

↪2nd side = 23m

↪3rd side =9m
