A) 864 sq. m
B) 764 sq. m
C) 854 sq. m
D) 754 sq. m
Correct Answer: A
Solution :
Let the length of the sides be \[3x,4x,5x\]meters. \[\Rightarrow \]\[144=12x\Rightarrow x=12\] \[\therefore \]Sides of the triangular field are 3 6m, 48m, 60 m. \[\Delta =\sqrt{72(72-36)(72-48)(72-60)}\] \[=864\,sq.\,m.\]You need to login to perform this action.
