How do I find the perimeter? Any help will be appreciated. Thank you :))

Perimeter of triangle CDE = 56

Step-by-step explanation:

Here, we want to find the perimeter of CDE

mathematically, when the measure of the inner triangle is half of the respective sides of the bigger

What this mean is that for each side that one of the side of the inner triangle faces, the measure on the bigger triangle is twice

Thus, 9 represents a length of 2(9) = 18 on the bigger triangle

Also, 7 will represent a length of 2(7) = 14 on the bigger triangle

So, now we have the complete sides of the bigger triangle

The measure of the perimeter is simply the addition of the respective side lengths

We have the perimeter of the large triangle as;

24 + 18 + 14 = 56
