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
