Question

The perimeter of the triangle is 6.9 meters. What is the unknown side length?

Answer 1

2

Explanation:

I didn't really put much effort into figuring this out, so tell me if it wrong, but I just added the two known side lengths which = 4.9 then did 6.9 - 4.9 = 2

If the answer is wrong I'm so sorry, I hope this question isn't for anything serious, like a final.

Answer 2

2

Explanation:

6.9-2.1=4.8

4.8-2.8=2
