What is the missing side length of an irregular pentagon with side lengths nineteen point nine centimeters, twenty-four point eight centimeters, thirty centimeters and forty-nine point two centimeters, if the perimeter is equal to the perimeter of a regular hexagon with side length twenty-six centimeters?

Question

19.9cm
24.8cm
30cm
49.2cm
and $x$cm  ($x$ is the missing side-length)
-----------------------------------
Now, the perimiter of this shape is equal to the perimeter of a regular hexagon with side length twenty-six centimeters.
Lets find this "perimeter of regular hexagon w/ side length 26 centimeters", 
hexagon = 6 sides
each side is 26, so all sides are 26•6=156

So the perimeter of our initial shape is 156

Now, all you need to do is to find the missing side.

Perimeter = The sum of all of the sides.

156 = 19.9 + 24.8 + 30 + 49.2 + $x$
And knowing all sides except one, and after we have found the sum, we have to solve for x (x is the missing side).
