Expert Answer:

begin mathsize 12px style If space AD space is space straight a space median space in space the space figure space and space AP space is space the space perpendicular comma
Area space of space ABC equals 1 half cross times AP cross times BC
Area space of space ADC equals 1 half cross times AP cross times CD equals 1 half cross times AP cross times BC over 2 equals 1 half cross times open parentheses 1 half cross times AP cross times BC close parentheses
equals 1 half cross times Area space of space ABC
Hence comma fraction numerator space area space of space ABC over denominator area space od space ADC end fraction equals 2
But space BC over AC space is space not space always space 2. space It space depends space on space the space triangle space ABC space and space measure space of space its space sides.
The space question space seem s space wrong. space Please space check space it space and space post space the space corrected space question.
