take a four foot level up to the roof and measure the distance from the bottom of the level to the roof and divide by 4. . .that is the pitch

Multiply the known length by 5, because the sides are all the same length on a regular pentagon and a pentagon has 5 sides.
By using Pythagoras' theorem.
Square the two sides then add them up and the square root of this sum gives the length of the hypotenuse
A square has 4 sides of equal length (say x). The diagonal length = x * (2)^0.5 = 1.414x, from Pythagorus's theorem. So, dividing the diagonal length by the square root of 2 will be the answer.
By measuring it
no
You can find the permeter if you know the length of the sides. You need to add the lengths of all the sides together.
subtract the two sides that you know from the perimeter to get the unknown side.
Not possible, you need at least the length of two sides and the included angle.
If you know the length of the sides but not the diagonal, you can use the Pythagorean Theorem.
This depends on the given information in the problem. All sides are equal, so if you can find one, you will know all the sides.
If you do not know the length and width of ALL sides, then as far as I know it isn't possible to find the perimeter unless you measure each side and then find it.
i can
You have to add up all the sides of the shape.
