Algebra.Com's Answer #63324 by rossiv53(27) ![]() You can put this solution on YOUR website! Ok, so begin by assigning a variable for width. \n" ); document.write( "Width = W \n" ); document.write( "We know that length is 5 feet less than twice the width. So, L=2W-5 \n" ); document.write( "Perimeter is equal to the value of all four sides. \n" ); document.write( "So, W+W+(2W-5)+(2W-5)=230 ft \n" ); document.write( "2W+2(2W-5)=230 \n" ); document.write( "2W+4W-10=230 \n" ); document.write( "6W-10=230 \n" ); document.write( "6W-10+10=230+10 \n" ); document.write( "6W=240 \n" ); document.write( "W=40 This is width \n" ); document.write( "L=2(40)-5 \n" ); document.write( "L=75 \n" ); document.write( "75+75+40+40=230ft \r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
