The perimeter of the triangle is 23.5 cm. One side of the triangle is 2 times smaller than the second side

The perimeter of the triangle is 23.5 cm. One side of the triangle is 2 times smaller than the second side, and the third is 4 cm smaller than the second. Find each side of the triangle.

1) One side of a triangle is x centimeters.

2) The other side of the triangle is x * 2 = 2x centimeters.

3) The third side of the triangle is (2x – 4) centimeters.

4) Let’s compose and solve the equation.

x + 2x + (2x – 4) = 23.5;

x + 2x + 2x – 4 = 23.5;

x + 2x + 2x = 23.5 +4;

5x = 27.5;

x = 27.5 / 5;

x = 5.5;

Answer: One side of the triangle is x = 5.5 centimeters, the other side of the triangle is x * 2 = 5.5 * 2 = 11 centimeters, the third side of the triangle is 2x – 4 = 2 * 5.5 – 4 = 11 – 4 = 7 centimeters.
