Pentagon.
Is Erne you add the out side of a shape
It depends. If the shape is a regular polygon (square, pentagon etc), multiply the number of sides by the length of one side. If it's an irregular polygon, add the lengths of each side together to find the perimeter.
if the shape is not labled on all the sides, then you measure each side and add the numbers together. if it is labled, then you just add the numbers on each side
If the shape is labeled on each side just add them together, but if it is not, measure the sides then add them together.
Break up the odd shape into even shapes and add the areas.
There is no such shape since it is always possible to add another side.

No that gives you the perimeter. The area depends on the shape. For example the area of a square is length of the side squared, and the area of a rectangle is the length of one side times the length of the base.
360 degrees In a parallelogram, all the angles will add up to 360 degrees. Think of a square.
The interior angles in a quadrilateral (4 sided shape) add up to 360 degrees.
It is square because when you add it up then you subract and add triangle then you calulate the sides and get triangle
To find the perimeter of a shape, you add up the lengths of all its sides. Since a square has four equal sides, the perimeter of a square is calculated by multiplying the length of one side by 4. In this case, if the area of the square is 25 square units, it means each side is 5 units long. Therefore, the perimeter would be 5 units x 4 sides = 20 units.
