Algebra.Com's Answer #670008 by addingup(3677)![]() ![]() You can put this solution on YOUR website! 45*3= 135 this is the perimeter of the triangle and the rectangle \n" ); document.write( "L = 2W, thus: \n" ); document.write( "2(2W)+2W = 135 \n" ); document.write( "4W+2W = 135 \n" ); document.write( "6W = 135 \n" ); document.write( "W = 22.50, and since the length is twice the width: \n" ); document.write( "L = 22.5*2 = 45 \n" ); document.write( "---------------------------- \n" ); document.write( "Check: \n" ); document.write( "2(22.5)+2(45) = 135 \n" ); document.write( "45+90 = 135 Correct \n" ); document.write( ": \n" ); document.write( "John \n" ); document.write( " |
