How do I find the area of a space?

To find the total area of a square or rectangular space, it is necessary to multiply the length by the width. The product of this multiplication is expressed in square units. Finding the area of a circular space requires multiplying the square of the radius by pi.

Calculating the area of irregular shapes is more complicated. Often, the best approach is to divide the irregular polygon into more-familiar and easier-to-calculate areas. Once area figures have been attained for each section of the irregular shape, these figures can be added together to arrive at the total area for the entire space.
