the area of a trapizoid is 108cm squared the height is 12cm and the length of one parrallel sides is 8cm. find the length of the 2nd parallel side.
\n" ); document.write( ".
\n" ); document.write( "area of any trapezoid is:
\n" ); document.write( "((b1 + b2)/2)h
\n" ); document.write( ".
\n" ); document.write( "where
\n" ); document.write( "b1 is length of one parallel side
\n" ); document.write( "b2 is length of opposite parallel side
\n" ); document.write( "h is height
\n" ); document.write( ".
\n" ); document.write( "plugging in what was given:
\n" ); document.write( "Let x = length of 2nd parallel side:
\n" ); document.write( "108 = ((8 + x)/2)(12)
\n" ); document.write( "108 = (8 + x)(6)
\n" ); document.write( "18 = (8 + x)
\n" ); document.write( "10 cm = x
\n" ); document.write( " \n" ); document.write( "
\n" );
