How to Calculate Land Area At Site?

HERONS FORMULA.

Area =

Where,

s = semi perimeter

S = ( a + b + c ) / 2

LAND OR PLOT

In ∆ ABD

AB ( a ) = 6 m

BD ( b ) = 8 m

AD ( c ) = 10 m

S = ( a + b + c ) / 2

= ( 6 + 8 + 10 ) / 2

= 12 m

Area =

Area =   24 m²

In ∆ BCD

BC ( a ) = 6 m

CD ( b ) = 6 m

BD ( c ) = 8 m

S = ( a + b + c ) / 2

S = ( 6 + 6 + 8 ) / 2

S = 10 m

Area =

Area = 17.88 m²

In ∆ ADE

AD ( a ) = 10 m

DE ( b ) = 8 m

AE ( c ) = 4 m

S = ( a + b + c ) / 2

S = ( 10 + 8 + 4 ) / 2

S = 11 m

Area =

Area =  12.40 m²

Total Area of Land

Area = ∆ ABD + ∆ BCD + ∆ ADE

Area = 24 + 17.88 + 12.40

Total Area =   54.28 m²
