a) Draw a line AB. Let the midpoint of AB be X.
Realise that AX = DM and BX = CM
Use trigo to find AOX. Then AOB = 2 x AOX
b) use Pythagoras' theorem to find XO. Then MX = MO - XO.
AD = MX
c) As angle AOB is found, use it to find length of arc AMB. From there you can find the perimeter
d) Find segment AMB. Subtract it from rectangle ABCD to get your answer.

There could be a misinterpretation of information. DM=4

Zoom in after clicking on the picture, if too small. Take a screenshot, if needed.
You can add your on point to the diagram, but draw a simple sketch of the diagram as part of your answer, so the examiner knows which points you added.
