The perimeter of the triangle is 48 cm. The length of one side is 16 cm, and the other is 18 cm. Find the length of the third side of the triangle.
1) From the data we know, we can find out the sum of the lengths of the two sides of the triangle, if we know that one side has a length of 16 cm, and the length of its second side is 18 cm.
16 + 18 = 34 cm.
2) Let’s find out what is the length of the third side of the triangle, if we learned that the sum of the lengths of its two sides was 34 cm, and the sum of the lengths of all its sides is 48 cm, which is the perimeter of the triangle.
48 – 34 = 14 cm.
Answer: The length of the third side of the triangle was 14 cm.
