Algebra.Com's Answer #556827 by tutoringisfun(17) You can put this solution on YOUR website! Good afternoon student. I hope this is helpful to you. \r \n" ); document.write( "\n" ); document.write( "In order to solve this problem, you have to know the formula for the perimeter of a rectangle, which is p=2L+2w \n" ); document.write( "L=length and w=width \n" ); document.write( " \n" ); document.write( "1. From the problem\r \n" ); document.write( "\n" ); document.write( "p=18 \n" ); document.write( "L=6\r \n" ); document.write( "\n" ); document.write( "2. substitute these values into the perimeter formula:\r \n" ); document.write( "\n" ); document.write( "18yd=2(6 yd) + 2w\r \n" ); document.write( "\n" ); document.write( "3. distribute\r \n" ); document.write( "\n" ); document.write( "18=12+2w\r \n" ); document.write( "\n" ); document.write( "4. Subtract 12 from each side\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "18-12=12-12+2w\r \n" ); document.write( "\n" ); document.write( "5. Simplify. The 12's on the right cancel out leaving:\r \n" ); document.write( "\n" ); document.write( "6=2w\r \n" ); document.write( "\n" ); document.write( "6. Divide by 2 because you want w by itself\r \n" ); document.write( "\n" ); document.write( "6/2=2w/2\r \n" ); document.write( "\n" ); document.write( "simplify this answer leaving:\r \n" ); document.write( "\n" ); document.write( "3=w\r \n" ); document.write( "\n" ); document.write( "to check your answer substitute all three variables into the perimeter formula and solve:\r \n" ); document.write( "\n" ); document.write( "18=2(6)+2(3)\r \n" ); document.write( "\n" ); document.write( "18=18 therefore 3 is the correct answer. \r \n" ); document.write( "\n" ); document.write( "I hope this has been helpful to you.
