Description 



Area of a Polygon: A measurement of the region enclosed by the sides of a polygon. The area is always expressed in squared units. 
Common formulas for finding the areas of different polygons are listed below:
Square: A = s^{2} (s = length of a side)
Rectangle: A = l*w (l = length and w = width)
Parallelogram: A = b*h (b = base and h = height)
Triangle: A = (1/2)*b*h (b = base and h = height)
Trapezoid: A = (1/2)*h*(b_{1} + b_{2}) (h = height, b_{1} = base, and b_{2} = other base )
