To find the area of a rectangle, we need to find the length of one side and the width of the rectangle.
Using the given coordinates:
The length of the rectangle can be calculated as the distance between points (9, -1) and (5, -6):
Length = sqrt((5-9)^2 + (-6-(-1))^2) = sqrt(16 + 25) = sqrt(41)
The width of the rectangle can be calculated as the distance between points (-1, 7) and (-5, 2):
Width = sqrt((-5-(-1))^2 + (2-7)^2) = sqrt(16 + 25) = sqrt(41)
Now, the area of the rectangle can be found by multiplying the length and width:
Area = Length * Width = sqrt(41) * sqrt(41) = 41 square units
So, the correct answer is:
41 square units.
