Algebra.Com's Answer #1997 by arunpaul(104)![]() ![]() ![]() You can put this solution on YOUR website! let length of room = l \n" ); document.write( " width of the room = w \n" ); document.write( "as per the question l = w + 5' \n" ); document.write( "the perimeter of room = 70' \n" ); document.write( "or 2(l+w) = 70 \n" ); document.write( "putting the value of l in the above equation we have \n" ); document.write( " 2(w+5+w) =70 \n" ); document.write( "or 2w +5 = 70/2 \n" ); document.write( "or 2w = 35 - 5 \n" ); document.write( "or 2w = 30 \n" ); document.write( "or w = 30/2 \n" ); document.write( "or w = 15' \n" ); document.write( "so putting the value of w in l \n" ); document.write( "we have length of room = l = w + 5 = 15 + 5 = 20\r \n" ); document.write( "\n" ); document.write( "so length = l = 20 feet \n" ); document.write( " width = w = 15 feet (Ans) \n" ); document.write( " \n" ); document.write( " |
