Answer:
Step-by-step explanation:
The co-ordinates of the rectangle are:
A (8, 6)
B (-4, -10)
C (-8, -7)
D (4, 9)
The Area of Rectangle is Given by: <em>length x breadth </em>= AB x BC
Lengths of AB and BC can be found by distance formula
<em>length</em>(AB) =
= 
Similarly,
<em>length</em>(BC) = 5
Area of Rectangle = AB x BC = 20 x 5 = 100 square units

Step-by-step explanation:
<em>The question is incomplete as the image that illustrates the scenario is not given.</em>
<em>However, I can deduce that the question is about a right-angled triangle.</em>
<em>So, I will give a general explanation on how to find each of the side of the triangle, given a side and an angle.</em>
