Answer: Choice D) 100 square meters
=============================================================
Step-by-step explanation:
Refer to the diagram below.
Use the distance formula to find the distance from A to B
A = (9,0)
B = (17,6)
Segment AB is 10 units long.
Repeat the distance formula to find that segment BC is 15 units long.
That makes the area of red rectangle ABCD to be 10*15 = 150 square meters.
Again, using the distance formula, you should find that EF = 5 and FG = 10, so the area of the blue rectangle EFGH is 5*10 = 50 square meters
---------------
The border area is the difference of the two rectangle areas
border area = (red rectangle area) - (blue rectangle area)
border area = (150) - (50)
border area = 100 square meters
That's why the answer is choice D
