Hi there, \n" ); document.write( "Say you have a square that measures \n" ); document.write( "40m x 40m \n" ); document.write( "Area = 1600m^2 \n" ); document.write( "If you increase one pair of sides by 40% \n" ); document.write( "they will equal 56m \n" ); document.write( "The other pair of sides increased by \n" ); document.write( "30% will equal 52m \n" ); document.write( "New area = 56 x 52 = 2912m^2 \n" ); document.write( "2912m^2 - 1600m^2 \n" ); document.write( "= 1312m^2 \n" ); document.write( "=1312m^2/1600m^2 x 100 \n" ); document.write( "= 82% \n" ); document.write( "Hope this helps:-) \n" ); document.write( " |
