abe just built a pool in his backyard. he wants to build a fence around the entire area to make sure no one falls in accidently. abe's backyard is 15 meters wide and 25 meters long. it costs $9.00 per meter to install a wooden fence. how much would it cost to install a fence around his entire backyard?
a$135
b$360
c$225
d$720

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
