The formula for the area of a trapezoid is
\n" ); document.write( "A = (h/2)(b1 + b2)
\n" ); document.write( "Here h = 10, b1 = 2/3(b2), and A = 125...now plug in
\n" ); document.write( "125 = (10/2)(b + (2/3)b)
\n" ); document.write( "25 = (5/3)b
\n" ); document.write( "b = 15 cm
\n" ); document.write( "2/3 b = 10 cm
\n" ); document.write( "
\n" );
