The answer is 1014 squared
You split them into three shapes 1,2,and 3. They are each a rectangle, so the area formula is l•w. For 1. It is 6•39=234.For 2. It is 6 and if it is 28 and the whole side is 39 then you subtract and get 13 . So for 2. It is 6•13=78.For 3. It is 39•18=702.After that you add 234+78+702 , which gives you your answer of 1014 . But you always have to square it , so the answer is 1024 squared
