L * W = A
\n" ); document.write( "L * W = 20m^2
\n" ); document.write( ".
\n" ); document.write( "If you increase the length by 3 and the width by 1, the area will then be twice as large.
\n" ); document.write( "(L+3) * (W+1) = 40m^2
\n" ); document.write( ".
\n" ); document.write( "Here's one way to do it:
\n" ); document.write( "The factors of 40 are -
\n" ); document.write( "40,1
\n" ); document.write( "20,2
\n" ); document.write( "10,4
\n" ); document.write( "8,5
\n" ); document.write( "The factors of 20 are -
\n" ); document.write( "20,1
\n" ); document.write( "10,2
\n" ); document.write( "5,4
\n" ); document.write( "Which of the factors of 20 can be put into the equation (L+3) * (W+1) = 40m^2 to make it true?
\n" ); document.write( "Only 5,4 (which becomes 8,5) is possible.
\n" ); document.write( "The original dimensions are 5m x 4m. The revised dimensions are 8m x 5m.
\n" ); document.write( "
\n" ); document.write( "
\n" );
