The sides of a triangle are three consecutive hold numbers the perimeter of the triangle is 45 cm how long is each side

1 answer

Let the three consecutive odd numbers be x, x+2, and x+4. The perimeter of a triangle is the sum of the lengths of its three sides, so we have:

x + (x+2) + (x+4) = 45

Combining like terms, we get:

3x + 6 = 45

Subtracting 6 from both sides, we get:

3x = 39

Dividing by 3, we get:

x = 13

Therefore, the three sides of the triangle are 13 cm, 15 cm, and 17 cm.
