First, we need to know the sides of the equilateral triangle
Side = 36 / 3
Side = 12 cm.
The formula of getting the Area of an equilateral triangle is:
Area = square root (3) / 4 * a^2
Area = square root (3) / 4 * 12^2
Area = 62.3538 cm^2
Approximately, the area is equal to 62 square centimeters. The correct answer is letter B.
