Algebra.Com's Answer #499319 by Seutip(231)![]() ![]() You can put this solution on YOUR website! Let x- be the width\r \n" ); document.write( "\n" ); document.write( "In finding the Perimeter, we use the formula \n" ); document.write( "P=2length+2width\r \n" ); document.write( "\n" ); document.write( "So, \n" ); document.write( "240 = 2(99) + 2x \n" ); document.write( "240 = 198 + 2x \n" ); document.write( "42 = 2x \n" ); document.write( "21 = x\r \n" ); document.write( "\n" ); document.write( "So the width should be 21 cm, to have a length of 99 cm and a perimeter of 240 cm.\r \n" ); document.write( "\n" ); document.write( "Hope that helps! :) \n" ); document.write( " |
