Question 1002850: find the area of the rectangle whose vertices are the points with coordinates (5,2),(5,-6),(0,-6),(0,2)
Answer by Cromlix(4381)   (Show Source):
You can put this solution on YOUR website! Hi there,
Plotting out the points it would
appear that the length of the rectangle
is represented by(0,2) and (0 -6)
Using distance formula
Sqrt (x2 - x1)^2 + (y2 - y1)^2
Sqrt (0 - 0)^2 + (-6 - 2)^2
Sqrt (-8)^2
Sqrt 64 = 8 units
The width is represented by
(0,2) and (5,2)
Using distance formula
Sqrt (x2 - x1)^2 + (y2 - y1)^2
Sqrt(5 - 0)^2 + (2 -2)^2
Sqrt (5)^2
Sqrt 25 = 5 units
Area = length x width
Area = 8 x 5
Area = 40 units^2
Hope this helps :-)
