x= width
\n" ); document.write( "length is (4x+16)
\n" ); document.write( "Area is x*(4x+16)=4x^2 +16x
\n" ); document.write( "That would be a rectangle of width 5 and length 36
\n" ); document.write( "Area is 180.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Equivalent polynomial with area 180
\n" ); document.write( "length would be 20 and width 9.\r
\n" ); document.write( "\n" ); document.write( "A rectangle has length 7 less than three times the width.\r
\n" ); document.write( "\n" ); document.write( "width=y
\n" ); document.write( "length=3y-7
\n" ); document.write( "area= 3y^2-7y\r
\n" ); document.write( "\n" ); document.write( "A polynomial with equivalent area would be a rectangle with the width twice the previous example and the length 8 more than the width.\r
\n" ); document.write( "\n" ); document.write( "Then the width would be 2x and the length (2x+8). Area is 2x*(2x+8)= 4x^2 +16x.\r
\n" ); document.write( "
