What is the area of a rectangle with vertices at (4,3), (1,3), (11,9) and (4,9)

.

18 units^2.

Step-by-step explanation:

First find the length of 2 adjacent sides:

One length ( between the first 2 given points)  =  √ [ (4-1)^2 + (3-3)^2]

=  3.

The length of the adjacent side = √ [ (1-1)^2 + (3-9)^2 ]

=  6.

So the required area = 3 * 6  

= 18.
