Such a pentagon is impossible.
A regular pentagon, with side lengths of 26 m has a perimeter of 5*26 = 130 metres.
Four sides of the irregular pentagon are 19.9 cm, 24.8 cm, 30 cm and 49.2 cm making a total of 123.9 cm. The length of the fifth side must be less than 123.9 cm. Therefore the perimeter of the irregular pentagon must be less than 247.8 cm - less than 2% of the required length of 130 metres or 13,000 cm.
Perimeter = 5*26 = 130cm Missing length = 130-23.3-30.4-44.9 = 31.4cm
In order to find the perimeter of a 3D rectangle you must gather the lengths of the known sides, calculate the missing rectangular values, and use the formula for perimeter.
Surely you know how to find the third side of a right triangle, when you know the lengths of the other two. Find it, and then add up the lengths of the three sides to get the perimeter.
To create a triangle, the sum of the two shorter sides must be greater than the third side.If the side of length 14 is the longest side then the missing side must be greater than 14 - 10 = 4If the missing side is the longest side then the missing side must be less than 10 + 14 = 24Thus any length that is greater than 4 and less than 24.Examples include: 16, 5, 8, 10.
For a triangle to exist, the sum of the two shorter sides must be longer than the longest side. If 15 is the longest side, then the other, missing, shorter side must be greater than 15 - 4 = 11. If the third, missing, side is the longest side, then it must be less than 15 + 4 = 19 So the third side is any length greater than 11 and less than 19. Examples include 12, 13, 15, 11.5, 18.5.
A regular pentagon with side length 26 cm has a perimeter of 26*5 = 130 cm. The three sides of the quadrilateral sum to 98.6 cm so the fourth side must be 130-98.6 = 31.4 cm.
Perimeter = 5*26 = 130cm Missing length = 130-23.3-30.4-44.9 = 31.4cm

Depends on what information you have and what you require. If you have all three sides, there are different formulae to find the perimeter, angles and area. If you have two sides and an angle (depending on the angle) you have formulae for the remaining side and then perimeter and area. If you have a side and two angles there are formulae to find the missing sides and then perimeter and area. There are other possibilities: you have the altitude and require the area; etc.

14cm and 11cm what is the missing side using pythagorean theorem
A bit of missing wording here?
There is no standard formula. The answer will depend on the compound shape and also on which of the lengths (or angles) are known.
It depends on what is known about the triangle.
