What is area formula?
Given a rectangle with length l and width w, the formula for the area is: A = lw (rectangle). That is, the area of the rectangle is the length multiplied by the width. As a special case, as l = w in the case of a square, the area of a square with side length s is given by the formula: A = s2 (square).

How is the radius of a circle related to its area?
This distance from the center to any point on the circle is called the radius. More detail can be found regarding circles on the Circle Calculator page, but to calculate the area it is only necessary to know the radius, and understand that values in a circle are related through the mathematical constant π.
How to calculate the area of a quadrilateral?
It is one of the simplest shapes, and calculating its area only requires that its length and width are known (or can be measured). A quadrilateral by definition is a polygon that has four edges and vertices.
How to calculate the area of a piece of land?
area = length × width. The Farmer and his Daughter – Unsold Land. Imagine a farmer trying to sell a piece of land that happens to be perfectly rectangular. Because he owns some cows that he did not want frolicking freely, he fenced the piece of land and knows the exact length and width of each edge.
How to calculate the area of a shape?
The following are calculators to evaluate the area of seven common shapes. The area of more complex shapes can usually be obtained by breaking them down into their aggregate simple shapes, and totaling their areas. This calculator is especially useful for estimating land area.
