Question

answer is 23,23,9
but i need step by step solution​

Answer 1

Step-by-step explanation:

Given:-

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

Perimeter of the triangle is 55m.

To find:-

The dimensions of the triangle.

Solution:-

Let the third side be X m

Then,The equal sides are 4m less than 3times the third side.

Equal sides are (3X-4)m each

The perimeter is the sum of all sides

=>Perimeter=3X-4+3X-4+X

=>Perimeter= (7X-8) m

But , according to the problem

Perimeter is 55 m

=>7X-8=55

=>7X=55+8

=>7X=63

=>X=63/7

=>X=9m

The third side =9m

The equal sides are 3X-4=3(9)-4=27-4=23m

Answer:-

The three sides are 23 m,23m and 9m

Check:-

Perimeter=23+23+9=55m
