Solve for ( L ): ( L = 240 - 2W ). Substitute: ( A(W) = (240 - 2W) \times W = 240W - 2W^2 ). Domain: ( W > 0 ) and ( L > 0 ) → ( 240 - 2W > 0 ) → ( 0 < W < 120 ). Let $x$ = width (perpendicular to river), $y$
If the problem asks for dimensions, provide both (e.g., "The dimensions are 20ft by 40ft"). If it asks for the maximum area, provide the final calculated value (e.g., "800 sq ft"). The "Endpoints" Rule: If your domain is closed (like Substitute: ( A(W) = (240 - 2W) \times W = 240W - 2W^2 )
