Answer:

38.042 square units

Explanation:

Steps to find the area of a regular polygon with 20 sides and a side length of 2

Find the apothem

apothem = s / (2 * tan(pi/n))

apothem = 2 / (2 * tan(pi/20))

apothem ≈ 1.9021

Calculate the perimeter

perimeter = n * s

perimeter = 20 * 2

perimeter = 40

Calculate the area

area = (1/2) * apothem * perimeter

area = (1/2) * 1.9021 * 40

area ≈ 38.042 square units

Therefore, the area of the regular polygon with 20 sides and a side length of 2 is approximately 38.042 square units.
