Algebra.Com's Answer #532077 by JulietG(1812)![]() ![]() You can put this solution on YOUR website! A perimeter is a fence around. 2 lengths and 2 width = perimeter (2W + 2L = P) \n" ); document.write( "L = W + 9 \n" ); document.write( "Substitute the value of L from the second equation into the first. \n" ); document.write( "2W + 2(W+9) = 66 \n" ); document.write( "Distribute \n" ); document.write( "2W + 2W + 18 = 66 \n" ); document.write( "Add \n" ); document.write( "4W + 18 = 66 \n" ); document.write( "Subtract 18 from each side \n" ); document.write( "4W = 48 \n" ); document.write( "Divide each side by 4 \n" ); document.write( "W = 12 \n" ); document.write( ". \n" ); document.write( "If the width is 12, then the length is 12+9, or 21. \n" ); document.write( " |
