Step-by-step explanation:

The general formula for the lateral surface area of a regular pyramid is LSA=21Pl where P represents the perimeter of the base and l is the slant height.

Since the lateral surface area of the pyramid is P=360 m2 and the slant height is l=18 m, therefore, the perimeter of the pyramid is:

LSA=21Pl⇒360=21×P×18⇒360=9P⇒P=9360=40

Hence, the perimeter of the pyramid is 40 m2
