To calculate the area of a rectangular piece of land, measure its length and width. The area is then derived by simply multiplying the two figures gathered. For example, a piece of land that is 20 meters long and 10 meters wide has an area of 200 square meters.
Calculating the area of a parcel of land becomes complicated when it is irregularly shaped. One way to go about doing this is to divide the land area into smaller rectangles or squares, calculate the area of each rectangle or square, and then add the computed figures.
The formula for finding the area of a square is basically the same as for a rectangle. The only difference is that a square has its length and width equal.
