Calculate the perimeter of a hexagon, three sides of which are 8cm, and the other three are 10cm.

In order to calculate the perimeter of a hexagon, you need to find the sum of the lengths of all its sides. According to the problem statement, a given hexagon has three sides, the length of which is 8 cm, and three sides of which are 10 cm long. Therefore, we can find the perimeter of this hexagon.

P = 8 + 8 + 8 + 10 + 10 + 10;

Or:

P = 8 * 3 + 10 * 3;

P = 24 + 30 = 54 cm.

Answer: The perimeter of the given hexagon is 54 cm.
