the two sides have lengths
x = 36 cos25°
y = 36 sin25°
and the perimeter, as usual is
p = 2(x+y)
this is assuming it is a rectangle, and not just a parallelogram, where more information would be needed.
The diagonal of rectangle is 36 meters long and makes an angle of 25° with one side of rectangle. Find the perimeter of the parallelogram.
