Algebra.Com's Answer #407896 by ptaylor(2198)![]() ![]() You can put this solution on YOUR website! Perimeter of Rectangle(P) equals 2*Length plus 2*Width or P=2L+2W \n" ); document.write( "Let W=width \n" ); document.write( "Then Length (L)=5W-3\r \n" ); document.write( "\n" ); document.write( "Sooooo \n" ); document.write( "P=2*(5W-3)+2*W simplify \n" ); document.write( "66=10W-6+2W add 6 to both sides \n" ); document.write( "12W=72 \n" ); document.write( "W=6ft----width of rectangle \n" ); document.write( "L=5*6-3=27 ft----length of rectangle\r \n" ); document.write( "\n" ); document.write( "CK \n" ); document.write( "2*27+2*6=66 \n" ); document.write( "54+12=66 \n" ); document.write( "66=66\r \n" ); document.write( "\n" ); document.write( "Hope this helps---ptaylor \n" ); document.write( " \n" ); document.write( " |
