The perimeter of an equilateral triangle is at least 24 cm. Estimate the length of one side of this triangle.

If the triangle is equilateral, then all its sides are equal. Since the perimeter is the sum of all sides, in the case of an equilateral triangle, the perimeter can be represented as the triple side of the triangle:

P = a + a + a = 3 * a;

So, knowing the lower boundary of the perimeter, you can similarly estimate the length of the side of the triangle. One side of an equilateral triangle with a perimeter of at least 24 cm, in length will be at least:

a = P: 3 = 24: 3 = 8 cm.
