Perimeter = 15 cm
Step-by-step explanation:
The equation P=5s represents the perimeter P of a regular pentagon with side length s.
We need to find the perimeter of a regular pentagon with side length of 3 cm.
To find it, put s = 3 cm in the given equation.
P = 5(3) cm
= 15 cm
Hence, the perimeter of the regular pentagon of side length 3 cm is 15 cm.
