I don't know what is meant by "a pattern by joining pentagons"?
A pentagon has 5 sides.
If, each side = 1,
Perimeter P = 1 + 1 + 1 + 1 + 1 = 5
Therefore, n pentagons = 5n
What if we made a pattern by joining pentagons? If the length of each side of the pentagon is 1 unit, then what would be the perimeter of n pentagons joined together? Note: The perimeter is the distance around the outside of the figure.
