Answer:
C. 12 square units
Step-by-step explanation:
Length of side E'F' = EF*scale factor = 3*2 = 6 units
Length of side D'E' = DE*scale factor = 1*2 = 2 units
Area of rectangle = length * width
Therefore, area of rectangle D’E’F’G’ = length of side E'F' * length of side D'E' = 6*2
area of rectangle D’E’F’G’ = 12 square units
