NEED THE ANSWER AS SOON AS POSSIBLE PLEASE!! ​

Answer 1

`\large \boxed{\sf \ \ (1)/(2)√((x_1^2+y_1^2)(x_2^2+y_2^2)) \ \ }`

Explanation:

Hello,

This is a right triangle so the area is:

`(1)/(2) \left\{ √(x_2^2+y_2^2) \cdot √(x_1^2+y_1^2) \right\}\\\\=(1)/(2)√((x_1^2+y_1^2)(x_2^2+y_2^2))`

Hope this helps.

Do not hesitate if you need further explanation.

Thank you
