The calculation of plot area is critical for both government officials and landowners. The government requires this data as part of a land survey, whereas the owners use this information to determine the exact land area they have and then use it in the best way possible. The process is complicated and involves a lot of math and formulas. Please bear with me as I explain how to calculate the plot area in this section.

**How do you calculate the land area? **

It would have been easier to put the formula and values in place and calculate the plot area if plots had been divided into the usual geometrical shapes. But this is not the case. The fields typically appear in the following forms:

- Stories in squares or rectangles
- Polygon plots with irregular edges
- Triangle plot

It will be easy to determine if you have a square or rectangular land. Here’s how you might go about it:

(Length x Length) = Square plot Area

Therefore, the calculation will be as follows: if the plot’s length is 30 feet, then the area will

A square land area is (30 x 30).

A square of land has a 900-foot area.

**Square land area equals length times width. **

If your plot has a length of 30 feet and a width of 20 feet, the area will be:

Square land area equals length times width

The size of the rectangle: 30×20

A rectangular plot measures 600 feet.

**The area of the triangle is equal to (s(s-a) (s-b) (s-c)). **

Here, s represents half of the triangle’s perimeter, and a, b, and c represent its sides.

Consider a plot with three sides that span, respectively, 14 meters, 24 meters, and 18 meters long. Here is how to determine a triangular land area.

Triangle plot area equals (s(s-a) (s-b) (s-c))

S = (a+b+c)/2

S= (14+24+18)/2

s= 28

The triangular land area is equal to (28(28-14)(28-24)(28-18))

= √(28(14)(4)(10))

= √ 15680

= 125.2m, i.e., 1347.6 feet
