Area of rectangle = L * W = 750 m^2 -----(1) \n" ); document.write( "Perimeter = 2(L + W ) \n" ); document.write( "110 = 2(L + W) \n" ); document.write( "55 = L + W \n" ); document.write( "W = 55 - L ------(2) \n" ); document.write( " plug (2) in (1) \n" ); document.write( "L(55 - L) = 750 \n" ); document.write( " 55L - L^2 = 750 \n" ); document.write( "L^2 - 55L + 750 =0 \n" ); document.write( "(L -30)(L-25)=0\r \n" ); document.write( "\n" ); document.write( "L = 30 or L =25 \n" ); document.write( "if L = 3 0 W = 55-30 = 25 \n" ); document.write( "if L=25 then W = 55-25 = 30 \n" ); document.write( "therefore dimensions of Rectangle are 30m and 25m .\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
