One side of the triangle is 5.1 cm, which is 2.1 cm less than the second side and 0.7 cm more than the third. Find the perimeter of the triangle

To find the perimeter of a triangle, add the lengths of all three sides of the triangle. Let’s calculate what is the length of the second side.

5.1 + 2.1 = 7.2 cm.

We calculate what the length of the third side is 5.1 – 0.7 = 4.4 cm.

Let’s calculate what the perimeter of the triangle is.

5.1 + 7.2 + 4.4 = 16.7.
