Perimeter of a Triangle

To find the lengths of the sides of a triangle when the perimeter is given, we need to use the ratio of the sides. In this case, the sides of the triangle are in the ratio of 2:2:3, and the perimeter is 28 cm.

Let's assume the lengths of the sides are 2x, 2x, and 3x, where x is a common factor. According to the given ratio, the sum of the sides is 2x + 2x + 3x = 7x.

We know that the perimeter of the triangle is 28 cm, so we can set up the equation:

7x = 28

To solve for x, we divide both sides of the equation by 7:

x = 28 / 7 = 4

Now that we have the value of x, we can find the lengths of the sides:

Side 1: 2x = 2 * 4 = 8 cm Side 2: 2x = 2 * 4 = 8 cm Side 3: 3x = 3 * 4 = 12 cm

Therefore, the lengths of the sides of the triangle are 8 cm, 8 cm, and 12 cm.

Answer: The lengths of the sides of the triangle are 8 cm, 8 cm, and 12 cm.
