You can put this solution on YOUR website!
Let x be the unit value. Then the lenght is 6x and the width is 5x. You are told the area (product) is 120\r
\n" ); document.write( "\n" ); document.write( "\"120+=+5x+%2A+6x\"
\n" ); document.write( "\"120+=+30x%5E2\"
\n" ); document.write( "\"4+=+x%5E2\"
\n" ); document.write( "x = 2 and x = -2
\n" ); document.write( "Since a length is never negative, the unit value must be \"2\"
\n" ); document.write( "Then, the length is \"6%2A2\" = \"12\"
\n" ); document.write( "And the width is \"5%2A2\" = \"10\"
\n" ); document.write( "
\n" );
