Algebra.Com's Answer #108678 by nerdybill(7384)![]() ![]() You can put this solution on YOUR website! The width of a a rectangle is fixed 26cm. What length will make the perimeter greater than 94cm? The length must be greater than ??? cm. \n" ); document.write( ". \n" ); document.write( "Well the perimeter of any rectangle is: \n" ); document.write( "perimeter = L+L+W+W \n" ); document.write( "or \n" ); document.write( "perimeter = 2(L+W) \n" ); document.write( ". \n" ); document.write( "Now, if the width if fixed at 26cm and we want the perimeter greater than 94cm we get the equation: \n" ); document.write( "perimeter = 2(L+W) \n" ); document.write( "94 < 2(L+26) \n" ); document.write( "47 < L+26 \n" ); document.write( "21 cm < L \n" ); document.write( ". \n" ); document.write( "Therefore the length has to be greater than 21 cm.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
