please help with this beginner geometry thing please!!

Two regular pentagons are similar. one side of the pentagon is 3 m long, and the perimeter of the second pentagon is three times As long as the first pentagon. what are the lengths of each side of the second pentagon. please give an explanation and the answer. i have a few more

Well, if one side of your first pentagon is 3 meters (assuming that all 5 sides are of equal length), then the perimeter of that pentagon would be 15 m. If your second pentagon is 3 times the size, then the perimeter would be 15(3)=45 m. Knowing your second pentagon also has 5 sides, you would divide the perimeter of 45 by the number of sides (5). 45/5=9 m. The lengths of each side of the second pentagon are 9m

What kind of an explanation would you understand? Do you know what a "regular pentagon" **is**? Do you know what "perimeter" means?

If one side of a regular pentagon is 3 m long, what is the perimeter of that pentagon? If the perimeter of a second pentagon is 3 times as long as the perimeter of the first, what is the perimeter of the second pentagon? What is the length of each side?
