Calculate the perimeter of a triangle, one side of which is 18 cm, the other is 3 times less and the third is 14 cm. What is the perimeter of the triangle?
To find the perimeter of a triangle, you need to find the length of the unknown side and add all three lengths together.
Let us find the second side of the triangle if the problem says that it is three times smaller than the side with a length of 18 cm.
18 cm / 3 = 6 cm.
Now you can find the perimeter of this triangle.
18 cm + 6 cm + 14 cm = 38 cm.
Answer: the perimeter of the triangle is 38 cm.
