2. At a zoo, the panda exhibit has a composite-shaped sidewalk around it. The composite shape includes two semi-circles and two rectangles. The dimensions of the sidewalk are shown in the figure below. (a) Find the approximate area of the sidewalk. Use 3.14 to approximate π. Pls show work I don't understand

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
