A=(1/2)*h*sum of the two parallel sides or bases. smaller base is x, larger is 5x-19.
\n" ); document.write( "477=(1/2)*18(6x-19)
\n" ); document.write( "954=108x-342
\n" ); document.write( "108=1296
\n" ); document.write( "x=12 ft, shorter base and larger base is 41 feet
\n" ); document.write( "the sum is 53 feet, and product of that and 9 ft is 477 ft^2
\n" ); document.write( "41 feet ANSWER.
\n" ); document.write( "
