I think the answer is around 1.4 as you need to multiply the area by 1/9 after finding the real area.

The length of the shortest side is DC

<h3>How to determine the shortest side?</h3>

As a general rule in triangle;

The smallest angle in a triangle is opposite the shortest side.

Similarly, the largest angle in a triangle is opposite the largest side.

From the given figure of triangles, the smallest angle is angle CBD with a measure of 47 degrees.

The side opposite this angle is side length DC

Hence, the length of the shortest side is DC
