Answer:
160 units²
Step-by-step explanation:
Since the scale factor is 4, you can multiply both sides of 4 and 5 by 4.
This makes each side different, 4 x 4 = 16, 4 x 5 = 20
To calculate the area of a triangle, it is base x height / 2
In this case, it is 20 x 16 / 2
= 320 / 2
= 160
Triangle K's area is 160 units²
