Derivation of Area Under Acre to Kanal and Big Marla.

1 Acre= (40 *36) Karam

We Know, 1 Karam = 5’6” or 5.50 Feet

Therefore, 1 Acre = (36*5.5)*(40*5.5)

=198*220

=43560 Sqft.

Therefore, Area under 1 Acre= 43560 Sqft.

We Know 1 Acre=8 Kanals

Therefore 1 Kanal = 1Acre/8

=43560/8

=5445 Sqft

Therefore, Area under 1 Kanal = 5445 Sqft.

We Know, 1 Kanal= 20 Marla

Therefore 1 Marla= 1Kanal/20

= 5445/20

= 272.25 Sqft

Therefore, Area under 1 Marla=272.25 Sqft.

This is called Big Marla usually used in Revenue and Villages.
