Algebra.Com's Answer #7522 by venugopalramana(3286)![]() ![]() You can put this solution on YOUR website! let length of rectangle be L and width be W. \n" ); document.write( " area = L*W=13.5..........(1) \n" ); document.write( " perimeter = 2*(L+W) \n" ); document.write( " length of one side =L = 0.2 times perimeter=0.2*2*(L+W) \n" ); document.write( " L=0.4*L+0.4*W \n" ); document.write( " 0.6*L=0.4*W \n" ); document.write( " 1.5*L = W....substituting in (1)we get \n" ); document.write( " 1.5*L*L=13.5 \n" ); document.write( " L*L= 13.5/1.5 =9 \n" ); document.write( " L=3 \n" ); document.write( " hence W = 13.5/3 = 4.5 \n" ); document.write( " |
