$(1, 2)$ , $(1, 0)$ , $(- 1, 0)$

The distances between the given points are the length (l), width (w), and diagonal (d).

The distance between the three corners is:

$(1, 2)$ and $(1, 0)$ $\to$ $2$

$(1, 2)$ and $(- 1, 0)$ $\to$ $2 \sqrt{2}$

$(1, 0)$ and $(- 1, 0)$ $\to$ $2$

The diagonal is the longest distance and the width is the shortest distance, which means the $l = 2$ and $w = 2$ .

$l = 2$

$w = 2$

The area of a rectangle is $A = l \cdot w$ .

$A = l \cdot w$

Multiply $2$ by $2$ .

$A = 4$
