Answer:
150 square units
Step-by-step explanation:
The base of ΔXYZ is XY, 8-3 = 5 units in length. The height of ΔXYZ is XZ, 6-2 = 4 units in length. The area of ΔXYZ is then ...
A = 1/2bh
A = 1/2(5)(4) = 10 . . . . . square units
The area of a figure is multiplied by the square of the dilation factor, so the area of ΔX'Y'Z' is 4²×10 = 160 square units
The difference between the areas is ...
160 - 10 = 150 . . . . . square units difference
