The sides of a triangle are consecutive numbers. If the perimeter of the triangle is 240 m, find the length of each side

Let the first side be n.
Next side which is consecutive is n + 1
Next side which is consecutive is n + 1 + 1 = n + 2

So we have the sum of 3 consecutive numbers is 240.

We type in sum of 3 consecutive numbers is 240 into our search engine and we get:
79, 80, 81
