2.423

Step-by-step explanation:

Surface that is not water: 5.1 - 3.61 = 1.49

How many times water is bigger than not water: 3.61/1.49 = 2.423

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down

answer: i believe its b. if you sound out the sentences that sounds wrong.
