Answer: 82 sq. units .
Step-by-step explanation:
Let A (9, −1), B (−1, 7), C(−5, 2), D(5, −6) are the vertices of rectangle.
Then we plot them on graph ( as provided in attachment)
Length = AB
units [By distance formula :
]
units
Width = BC =
units

Area = length x width
= 
Hence, the area of the rectangle is 82 sq. units .
