Plzzzz help will give brainliest to right answer!! Picture down below

The area of Triangle K is 160

Step-by-step explanation:

First, the question explains how Triangle K was a scale factor of 4, with Triangle J being the original. To find the dimensions of Triangle K, you multiply Triangle J's measurements by 4:

4 x 4 = 16

5 x 4 = 20

Now we know the dimensions of Triangle K, it's time to find the area;

Formula for finding area of a triangle: (H x B) / 2

16 (Height) multiplied by 20 (Base) is 320.

Now, we divide 320 by 2 to find our

320 divided by 2 is 160.

160 will be your answer.
