2. Bo Diddly currently has a squash patch that measures 14 yards in length and 10 yards in width. Bo needs to expand the size of this patch so that the area will be seven times
larger than its current area. The amount that Bo adds to the length will be three times
more than the amount he adds to the width. What will be the length of the expanded
squash patch?

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
