The walls of the triangle are 0.8 m, 1.6 m and 2 m. The perimeter of a similar triangle is 13.2m.

The walls of the triangle are 0.8 m, 1.6 m and 2 m. The perimeter of a similar triangle is 13.2m. Find the walls of the second triangle.

The sides of such triangles are correspondingly proportional. Let’s solve the problem using the equation, where:

0.8x – the first side of the second triangle;

1.6x – the second side of the second triangle;

2x – the third side of the second triangle;

Let’s compose and solve the equations, knowing the perimeter of the second triangle:

0.8x + 1.6x + 2x = 13.2;

4.4x = 13.2;

x = 13.2 / 4.4;

x = 3;

0.8x = 0.8 * 3 = 2.4 m – the first side of the second triangle;

1.6x = 1.6 * 3 = 4.8 m – the second side of the second triangle;

2x = 2 * 3 = 6 m – the third side of the second triangle.

Answer: 2.4 m; 4.8 m; 6 m.
