(A)rea = (L)ength x (W)idth = 494 \n" ); document.write( "L = W + 7\r \n" ); document.write( "\n" ); document.write( "By substitution,\r \n" ); document.write( "\n" ); document.write( "A = (W+7)(W) = 494 \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "By factoring, we get: \n" ); document.write( "(W-19)(W+26)=0; W=19, W=-26(Disregard this since there is no negative width)\r \n" ); document.write( "\n" ); document.write( "So the dimensions are L=19+7=26ft and W=19ft. \n" ); document.write( " |
