Algebra.Com's Answer #626172 by fractalier(6550)![]() ![]() You can put this solution on YOUR website! 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( " |
