Algebra.Com's Answer #78017 by acchs_cheerleader(6)![]() ![]() ![]() You can put this solution on YOUR website! The formula for the perimeter of a rectangle is 2(l+w)=perimeter. To find the answer you do:\r \n" ); document.write( "\n" ); document.write( "1) 2(l+w)=P \n" ); document.write( "2) 2(3+w+w)=24 [ since the length is 3 inch greater it means add ] \n" ); document.write( "3) 2(3+2w)=24 [ you find the like terms and add ] \n" ); document.write( "4) 6+4w=24 [ you distribute the 2 by multiplying] \n" ); document.write( "5) 4w=18 [ you subtract 6 to both sides ] \n" ); document.write( "6) w = 4.5 [ you divide 4 to both sides ]\r \n" ); document.write( "\n" ); document.write( "________________________________________________________________________________\r \n" ); document.write( "\n" ); document.write( "CHECK:\r \n" ); document.write( "\n" ); document.write( "1) 2(l+w)=P \n" ); document.write( "2) 2(3+4.5+4.5)=24 \n" ); document.write( "3) 2(12)=24 \n" ); document.write( "4) 24=24 \n" ); document.write( " |
