Answer:

Step-by-step explanation:
Let
be the shaded area and
be the unshaded area, then we know that
(1). 
and
(2).
We solve for
in the first equation and get:

and put this into the second equation and get:




New cordinates are formed by adding 7 in x and subtracting 2 from y
A(−2, 2) =A ' (-2 +7 , 2 - 1 ) = A' (5,1)
B(−2, 4) = B' (-2 + 7 , 4 -1 )= B' (5,3)
C(2, 4) = C' (2 + 7 , 4 -1 )= C' (9,3)
