Manual Calculation of Area of a field
AREA CALCULATION
- Divide the above sketch into simple triangles.
They are ∆ABC and ∆ACD
and an offset 1 is found in this triangle.
- Let's calculate area of each triangle
- Area of Triangle ABC
= (932+614+682)/2
= (2228)/2
s = 1114
Area of ∆ABC = √s(s-a)(s-b)(s-c)
=√1114x(1114-932)(1114-614)(1114-682)
=√1114(182)(500)(432)
=√1114x(39312000)
=√43793568000
Area of ∆ABC =209269.12 Sq.Gn.Links
- Area of Triangle ACD s = (a+b+c)/2
- Area of Offset 1
= (600+768+932)/2
= (2300)/2
s = 1150
Area of ∆ACD = √s(s-a)(s-b)(s-c)
=√1150x(1150-600)(1150-768)(1150-932)
=√1150x(550)(382)(218)
=√1150x(45801800)
=√52672070000
Area of ∆ACD =229503.96 Sq.Gn.Links
Area of ∆DA1 = (1/2)*BH
= (1/2)*600*24
= (1/2)*14400
Area of offset1 =7200 Sq.Gn.Links
- Total Area of FMB/Naksha = Area of Triangle ABC + Area of Triangle ACD + Area of Offset 1
= 445973.08 Sq.Gn.Links
= 445973.08/100000
= 4.46 Acres
∴ The Total area of FMB/Naksha = 4.46 Acres
= 4 Ac 18 Guntas
= 1.80 Hectare
