To find the area of the rectangle just multiply the two edges together. In other words the area of a rectangle is the product of its length and width. The opposite sides of the rectangle are equal and parallel to each other.
That is A l x w where l is the length and w is the width of the rectangle.
Given the area and one dimension of a rectangle we can find the other dimension. Feet squared meters squared centimeters squared etc. The rectangle below has a covered area of 12 square units The space inside a two-dimensional shape is the area or the amount of covered shape. The equation for calculating the area of a rectangle is as follows.
