Find the Square or Rectangle Area (-1,12) , (6,7) , (1,0)

$(- 1, 12)$ , $(6, 7)$ , $(1, 0)$

Step 1

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

The distance between the three corners is:

$(- 1, 12)$ and $(6, 7)$ $\to$ $\sqrt{74}$

$(- 1, 12)$ and $(1, 0)$ $\to$ $2 \sqrt{37}$

$(6, 7)$ and $(1, 0)$ $\to$ $\sqrt{74}$

Step 2

The diagonal is the longest distance and the width is the shortest distance, which means the $l = 8.60232526$ and $w = 8.60232526$ .

$l = 8.60232526$

$w = 8.60232526$

Step 3

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

$A = l \cdot w$

Step 4

Multiply $8.60232526$ by $8.60232526$ .

$A = 74$
