if 1/a is the factor to scale down lengths, 1/a^2
\n" ); document.write( "is the factor to scale down area(1/4)(7.8) = 1.95
\n" ); document.write( "the new area is 1.95 ft2
\n" ); document.write( "you can check this
\n" ); document.write( "suppose the sides are 2 and 3.9
\n" ); document.write( "that gives an area of 7.8
\n" ); document.write( "scale them down by 1/2
\n" ); document.write( "sides are 1 and 1.95
\n" ); document.write( "the new area is 1*1.95 = 1.95
\n" ); document.write( "checks
\n" ); document.write( "
