Bagaimana caranya menghitung luas tanah yang tak/tidak beraturan?

Cara / Langkah Termudah untuk Mengukur dan Menghitung Luas Tanah yang
memiliki segi bangun yang tidak beraturan.

Contoh :

Apabila ada sebidang tanah segi empat berbentuk trapesium tidak beraturan, panjang masing-masing sisinya 25,5 m dan 24,5 m. Sedangkan dua
sisi lagi memiliki panjang 26,6 m dan 33, 5 m. Bagaimana cara mencari luasnya?

Secara matematis :

Garis sejajar dibagi dua x tinggi (tinggi disini adalah (26,6+33,5)/2 = 30,05 )

maka :

(25,5 m+24.5m) / 2 x 30,05 m = 751,25 m2

Secara Grafis/ CAD (tidak bisa saya uraikan disini) hasilnya : 740.1278 m2

Maka pendekatannya : 751,25 m2+740.1278 m2 / 2 = 745.6889 m2

Dibulatkan menjadi = 745.70 m2
