Answer:
Step-by-step explanation:
The first step is to use the Distance Formula to figure out the lengths of the two legs:
R(1, 1) and P(−1, −2) ↷
Q(2, −4) and P(−1, −2) ↷
* So, by my calculations, we have an isosceles <em>right triangle</em>, and according to the <em>45°-45°-90° triangle theorem</em>, we automatically know that the hypotenuse, <em>RQ</em>, is :
30°-60°-90° triangle theorem

So now, we have to find the area of the triangle by taking half of either height or base, then multiplying that by the height or base, but since this is an isosceles <em>right</em><em> </em><em>triangle</em><em>,</em><em> </em>it does not matter:
