Area Computation Using Cross coordinate method

AREA COMPUTATION PROCEDURE USING CROSS COORDINATE METHOD

To compute area of a parcel of land with vertices coordinates given below;

A. 843834.447, 651867.023

B. 843722.016, 652165.124

C. 844062.256, 652301.287

D. 844071.258, 652185.147

E. 843895.558, 651962.478

F. 843834.698, 651867.798

Step 1

Arrange the coordinates either clock wisely or anti clock wisely and repeat the first coordinate
Step 2

Cross multiply the coordinates as shown in the table below.

 

Step 3

Find the sum of A1 and A2

A1=3321852238488.840

A2=3321855341508.320

Step 4

Calculate your area using the below formula;
