Algebra.Com's Answer #53982 by scott8148(6628)![]() ![]() You can put this solution on YOUR website! The area of the picture is width X length or w(w+4)\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "The area of the picture and mat is; (w+4) (the width of the picture plus the mat, which is 2 inches on each side), multiplied by (w+4+4 or w+8) (the length of the picture plus the mat)\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "The difference in these two areas is the area of the mat itself (112) so (total area)-(area of picture)=(area of mat)\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "or (w+4)(w+8)-w(w+4)=112......looks like equation 3 is the winner \n" ); document.write( " |
