Answer 2

Step-by-step explanation:

$\huge\boxed{\fcolorbox{red}{Blue}{Answer}}$

length =x²+xy+y²

breadth=x-y

Area of rectangle =L x B

$l \times b = ( {x}^{2} + xy + {y}^{2} )(x - y)$

$= {x}^{2} (x - y) + xy(x - y) + {y}^{2} (x - y)$

$= {x}^{3} - {x}^{2}y + {x}^{2}y - x {y}^{2} + x {y}^{2} - {y}^{3}$

$= {x}^{3} - {y}^{3} \: is \: the \: correct \: answer$
