Let's find the perimeter and area.

Perimeter
A pentagon has 5 sides. Each side is 11 cm. All we need to do is multiply the length of each side by how man sides there are.
5×11=55

So, the perimeter is 55 cm.

Area
It's a very challenging formula for finding the area of a pentagon and there are calculators used for finding the area of shapes like the pentagon and that's what I used.

The area is 208.178 cm²
Perimeter: To calculate the perimeter is easy, just multiply 11cm by the number of sides, which in this case, is 5.

So 5 * 11cm = 55cm.

Area: To calculate the area, it's a bit more tricky, the formula is [tex] \frac{1}{4} \sqrt{5(5+2+ \sqrt{5} )} s^{2} [/tex].

Since it's very hard to do, I got a calculator and did it.

And the answer is: [tex] 208.18cm^{2} [/tex]

Hope this helped! c:
