document.write( "I began with 2l+2w=P\r

Algebra.Com's Answer #4760 by rapaljer(4671)![]() ![]() You can put this solution on YOUR website! \"2 feet less than 10 times its length\" means you must start with 10L and then take away 2 feet from this. It should be 10L-2, not 2-10L.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Solve this:\r \n" ); document.write( "\n" ); document.write( "2L + 10L-2 + 10L-2 = 62 \n" ); document.write( "22L - 4 = 62 \n" ); document.write( "22L = 66 \n" ); document.write( "L=3 = Length\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Then, 10L-2 = 10(3)-2= 28 = width.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Interesting, the length and the width seem to be reversed. It could be an oversight by the person who made up the problem. I've done it myself.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "R^2 at SCC\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
