The perimeter of the triangle is 24cm. The length of one side is 6cm and the other is 8cm. How long is the third party?

The perimeter of a triangle is found by the formula P = a + b + c, where P is the perimeter, a is the first side of the triangle, b is the second, c is the third.
According to the condition of the problem, we have: P = 24cm, a = 6cm, b = 8cm.
To find the length of the third side, it is necessary to subtract the lengths of two known sides from the perimeter of the triangle: c = P-a-b = 24-6-8 = 10 (cm).
Answer: the length of the third side is 10 cm.
