Algebra.Com's Answer #535860 by JulietG(1812)![]() ![]() You can put this solution on YOUR website! Perimeter (think, a fence around) equals 2 width + 2 length \n" ); document.write( "P = 2W + 2L \n" ); document.write( "18 = 2W + 2L \n" ); document.write( "Divide by 2 \n" ); document.write( "9 = W + L \n" ); document.write( "L = W+5 \n" ); document.write( "Substitute the value of L into the equation above it. \n" ); document.write( "9 = W+L \n" ); document.write( "9 = W+(W+5) \n" ); document.write( "9 = 2W+5 \n" ); document.write( "Subtract 5 from each side \n" ); document.write( "4 = 2W \n" ); document.write( "Divide each side by 2 \n" ); document.write( "2 = W \n" ); document.write( "If the width is 2, then the length is 5 more than that, or 7 \n" ); document.write( "W = 2; L = 7 \n" ); document.write( "P = 2+2+7+7, or 18 \n" ); document.write( " |
