WXYZ is a parallelogram where angle W is half of a right angle WX = 10, and XY = 144, What is the area of the parallelogram.
Since WXYZ is a parallelogram.....then angle X is supplementary to angle W = 135°
The area of the parallelogram = WX * XY * sin (135°) = 10 * 144 * (1/sqrt 2) = 1440 / sqrt 2 =
(1440) (sqrt 2 ) / 2 =
[720 * sqrt 2 ] units^2
