One side of the triangle is twice as large as the second, and the third side

One side of the triangle is twice as large as the second, and the third side is 5 cm less than the second. calculate the sides. triangle if its perimeter is 95.

Let’s define the sides of the triangle using the equation.

Let the first side of the triangle be 2x cm, the second x cm, and the third x 5 cm.

Let’s compose and solve the equation:

2x + x + x – 5 = 95;

4x – 5 = 95;

4x = 95 + 5;

4x = 100;

x = 100: 4;

x = 25 (cm) – the second side.

25 * 2 = 50 (cm) – the first side.

25 – 5 = 20 (cm) – third party.

Answer: a triangle has such side lengths: 50 cm, 25 cm and 20 cm.
