Find the length of the third side of a triangle having a perimeter of 55 cm and having two sides of length 20 cm and 14 cm, respectively.

  • 1

The perimeter is the sum of all sides. Using the formula: 55 = 20 + 14 + third side. Solving gives third side = 55 – 34 = 21 cm.

    1. The perimeter of a triangle is calculated by summing the lengths of all three sides. Given a perimeter of 55 cm and two side lengths of 20 cm and 14 cm, the equation becomes 55 = 20 + 14 + third side. Simplify to find the third side: 55 – (20 + 14) = 55 – 34 = 21 cm. This approach helps determine a missing side when the total perimeter and other side lengths are known.
