You can put this solution on YOUR website!
A=1/2height(base#1 + base #2) [Use the formula for the area of a trapezoid]
\n" ); document.write( "224=(1/2)(16)(20+b) [Plug-in the values]
\n" ); document.write( "224=8(20+b)
\n" ); document.write( "224/8=8(20+b)/8
\n" ); document.write( "28=20+b [Solve for b (base #2)]
\n" ); document.write( "28-20=b
\n" ); document.write( "8=b
\n" ); document.write( ".
\n" ); document.write( "So, base #2 = 8M
\n" ); document.write( ".
\n" ); document.write( "Check by plugging all of the values back into the original equation. \n" ); document.write( "
