![]() ![]() And, more generally, the area of any rectangle can be found by multiplying length times width. You can count the squares individually, but it is much easier to multiply 3 times 5 to find the number more quickly. The formulas you are going to look at are all developed from the understanding that you are counting the number of square units inside the polygon. These formulas help you find the measurement more quickly than by simply counting. Step 1: For calculating the perimeter of a rectangle, the Length (l) and Breadth (b) of the given figure are noted. Thus we get the standard formula of Perimeter of a rectangle (P). To help you find the area of the many different categories of polygons, mathematicians have developed formulas. P sum of all the four sides w w l l 2(w l), where w width, and l length. You can write “in 2” for square inches and “ft 2” for square feet.
