Find the Square or Rectangle Area (-2,11) , (4,6) , (-1,0)

$(- 2, 11)$ , $(4, 6)$ , $(- 1, 0)$

Step 1

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

The distance between the three corners is:

$(- 2, 11)$ and $(4, 6)$ $\to$ $\sqrt{61}$

$(- 2, 11)$ and $(- 1, 0)$ $\to$ $\sqrt{122}$

$(4, 6)$ and $(- 1, 0)$ $\to$ $\sqrt{61}$

Step 2

The diagonal is the longest distance and the width is the shortest distance, which means the $l = 7.81024967$ and $w = 7.81024967$ .

$l = 7.81024967$

$w = 7.81024967$

Step 3

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

$A = l \cdot w$

Step 4

Multiply $7.81024967$ by $7.81024967$ .

$A = 61$
