Hi, I’m Lena and I will be answering your question to the best of my ability. If you have any further questions after my answer, do not hesitate to ask me! ツ
♡ Let’s look at the main important thing(s) that will lead you in the correct path.
♥ The perimeter is the outside, it is <em>around</em> the figure. When you see those inner triangles, do not pay attention to them! They are just there to make your overthink the question.
♡ Let's solve!
♥ To begin, let's take LM. It already gives you half the segment, so all you need to do is double the number. 9*2=18.
♥ Now, let's take a look at NR. They already give you the segment as a whole, so you do not need to worry about it!
♥ Look at SR. You do the same thing as you did to LM, double the number. 8*2=16.
Now, we add all the numbers to get our final answer.
18+16+16=50.
It is a straight line of symmetry because if you have a paper A and you fold it, it will form a straight line, and that is also meaning a straight line of symmetry. If you fold it any other way, it will not be a line of symmetry.
Hope this helps you ;)
An octagon has 8 sides. Each side is given as 2a + 1
Perimeter = 8(2a + 1)
= 16a + 8
Answer: 16a + 8
Answer:
its area is square (11+17+4)
I guess this may help you
