Algebra.Com's Answer #412139 by sravanik2005(14)![]() ![]() ![]() You can put this solution on YOUR website! Let a,b,c be the lengths of sides \n" ); document.write( "and a,b be equal sides given c=2a-3 \n" ); document.write( "perimeter=a+b+c=41 \n" ); document.write( " a+a+2a-3=41 \n" ); document.write( "4a=44 =>a=11\r \n" ); document.write( "\n" ); document.write( "so,length of third side=2(11)-3=19ft \n" ); document.write( " |
