Area=A; x=width; L=length; P=perimeter
\n" ); document.write( "P=2(L+x)
\n" ); document.write( "600m=2(L+x) Divide each side by 2.
\n" ); document.write( "300m=L+x Subtract x from each side.
\n" ); document.write( "300m-x=L
\n" ); document.write( "A=Lx Substitute for L
\n" ); document.write( "A=(300m-x)(x)
\n" ); document.write( "\"A=-x%5E2-300xm%29\" ANSWER:A IN TERMS OF x.
