One side of the triangle is 20 cm, the other is three times more than the thirds

One side of the triangle is 20 cm, the other is three times more than the thirds. calculated the other two sides of the triangle if its perimeter is 52 cm

Let’s solve this problem through the equation. Let the length of the third side of the triangle be x centimeters, then the length of the second side is 3 * x centimeters. We know that the perimeter of a triangle is 52 centimeters and the first side of the triangle is 20 centimeters. Let’s make an equation. x + 3x + 20 = 52; x + 3x = 52 – 20; x + 3x = 32; x * (1 + 3) = 32; x * 4 = 32; x = 32: 4; x = 8 centimeters is the length of the third side of the triangle, then 3 * 8 = 24 centimeters is the length of the second side of the triangle.
Answer: 8 and 24 centimeters.
