Answer:
option B. 5 units.
Step-by-step explanation:
If a Δ XYZ is translated 4 units up and 3 units left to yield X'Y'Z'.
If we consider one vertex X (x, y) of the triangle XYZ then after translation X will form new vertex as
x' (x-3, y-4)
Then we have to find the distance between x and x' after translation.
In the figure attached we have to find the distance a.
a² = 3² + 4² ( By Pythagoras Theorem)
a² = 9 + 16
a = √25 = 5 units
Therefore, answer will be option B. 5 units.
The answer is B- 5 units
I got 224. 7(4)^2 = 112 •2 =224
