Algebra.Com's Answer #820565 by greenestamps(13200)![]() ![]() You can put this solution on YOUR website! \n" ); document.write( "I'm quite astonished by this problem. The statement of the problem is 100% correct both grammatically and mathematically. That is almost NEVER the case when a phrase like \"200% wider\" is used. \n" ); document.write( "I applaud the author of the problem for using correct English! \n" ); document.write( "\"A rectangular piece of fabric is 4 times as long as its width.\" \n" ); document.write( "Let the width be x; then the length is 4x. \n" ); document.write( "\"If it is 25% shorter and 200% wider...\" \n" ); document.write( "25% shorter means 75% as long; 75% of 4x is 3x. \n" ); document.write( "200% wider means the width is INCREASED by 200%, which means it becomes 100%+200% = 300% AS WIDE, or 3 times AS WIDE as it was; 3 times x is 3x. \n" ); document.write( "\"...it will become a square piece of fabric...\" \n" ); document.write( "Indeed it will be -- the length and width are both 3x. \n" ); document.write( "\"... with an area of 36 m^2\" \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "ANSWERS: width = x = 2m; length = 4x = 8m \n" ); document.write( " \n" ); document.write( " |
