Explicación paso a paso:
[tex]area = base \times altura[/tex]
[tex]area = (5x - 3y)(30x - y - 10)[/tex]
[tex]a = 150 {x}^{2} - 50x- 95xy + 3 {y}^{2} + 30y[/tex]
Para un área cuadrada sería:
[tex]a = (30x - y - 10)(30x - y - 10)[/tex]
[tex]a = 900x^{2} - 30xy - 300x - 30xy + {y}^{2} + 10y - 300x + 10y + 100[/tex]
[tex]a = 900 {x}^{2} - 60xy - 600x+ {y}^{2} + 20y + 100[/tex]
