Algebra.Com's Answer #11757 by venugopalramana(3286)![]() ![]() You can put this solution on YOUR website! LET THE SIDE OF THE SQUARE BE =X \n" ); document.write( "WHEN IT IS FOLDED INTO HALF WE GET A RECTANGLE OF SIDE X ON ONE SIDE AND X/2 ON OTHER SIDE.ITS PERIMETER=X+X/2+X+X/2...TAKING LCM 2 \n" ); document.write( "(2X+X+2X+X)/2=6X/2=3X..BUT PERIMETER =12...SO \n" ); document.write( "3X=12 CM \n" ); document.write( "X=12/=4 CM. \n" ); document.write( "HENCE AREA OF SQUARE =A*A=4*4=16...CAN YOU PLEASE TELL HOW YOU GOT 48 SO THAT WE CAN CORRECT YOUR WORKING AND TELL WHERE YOU HAVE GONE WRONG. \n" ); document.write( " |
