Answer: Lateral area of the pyramid is 144
Step-by-step explanation:
The formula for determining the lateral surface area of a regular pyramid is expressed as
Lateral area = (perimeter of base x slant height of pyramid) /2
From the information given,
Length of base = 12
Since the base is a square, the perimeter of the base is
4L = 4 × 12 = 48
Height of pyramid = 6
Therefore, lateral surface area of the pyramid is
(48 × 6)/2 = 288/2 = 144
