SEE THE TRAPEZOID ....ABCD below
\n" ); document.write( "AREA OF TRAPEZOID IS GIVEN BY
\n" ); document.write( "AREA=(1/2)*ALTITUDE*(SUM OF PARALLEL SIDES)=(1/2)*DA*(AB+CD)
\n" ); document.write( "WHERE ALTITUDE IS THE PERPENDICULAR DISTANCE BETWEEN PARALLEL SIDES =DA
\n" ); document.write( "PARALLEL SIDES ARE AB AND CD.
\n" ); document.write( "IN THE SAME FIGURE IF WE CONSIDER TRIANGLE.....ABD... AREA OF TRIANGLE IS GIVEN BY....AREA=(1/2)*BASE*ALTITUDE =(1/2)*AB*DA
\n" ); document.write( "WHERE ALTITUDE IS PERPEDICULAR HEIGHT FROM ONE VERTEX SAY D TO BASE AB THAT IS DA IN THIS FIGURE.
