Algebra.Com's Answer #54561 by tutorcecilia(2152)![]() ![]() You can put this solution on YOUR website! Use the formula for the perimeter of a rectangle: \n" ); document.write( "P=2(length + width) \n" ); document.write( "Plug-in the values \n" ); document.write( "108=2(3 1/4 + width) \n" ); document.write( "Change the fraction to a decimal \n" ); document.write( "108=2(3.25+width) [solve for w] \n" ); document.write( "108/2=3(3.25+w)/2 \n" ); document.write( "54=3.25+w \n" ); document.write( "54-3.25+2 \n" ); document.write( "50.75=w \n" ); document.write( ". \n" ); document.write( "check by plugging all of the values back into the original equation: \n" ); document.write( "P=2(length + width) \n" ); document.write( "108=2(3.25+50.75 \n" ); document.write( "108=2(54) \n" ); document.write( "108=108 [checks out]\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
