Algebra.Com's Answer #198876 by dabanfield(803)![]() ![]() ![]() You can put this solution on YOUR website! Suppose that te wideth of a rectangle is three feet shorter than length and that the perimeter of the rectangle is 84 feet. \n" ); document.write( "P= 2L + 2W \n" ); document.write( "a) Set up an equation for the preimeter incolving lony L, the length of the rectangle. \n" ); document.write( "84=2(3-x) + 2(x)? Is this right? \n" ); document.write( "b) Solove this euation algebraicall to find the length of the rectangle, Find the width as well\r \n" ); document.write( "\n" ); document.write( "You're on the right track. Since W = L-3 the second equation should be;\r \n" ); document.write( "\n" ); document.write( "84 = 2*L + 2*(L-3)\r \n" ); document.write( "\n" ); document.write( "Now you can solve the above for L then compute W = L-3. \n" ); document.write( " |
