There are several approximations, but easiest (I think) is shown below:
P=pi{3(a+b) - square root of: [(3a+b)(a+3b)]}
Where a=major axis (long diameter)
and b= minor axis (smaller one)

What is the name of a shape with 2 straight and 2 curved sides?
It is simply an elongated circle, possibly an oval but NOT an ellipse. It is not an ellipse because it has two straight sections. An ellipse is curved at all points along its perimeter.
What is the perimeter or circumference of an oval or ellipse?
It isn't possible to give a generalised formula for the circumference of an ellipse in terms of elementary functions. The circumference (or perimeter) of an oval is represented by an infinite series based on multiple aspects of the oval including: * Eccentricity * Implied length ("major radius") * Implied width ("minor radius")

What is the formula for finding the area of an ellipse?
the formula for finding the area of an ellipse is add it then multiply and subtract that is the final
What is the mathematical shape of an egg?
I think it's an ellipse. Ellipse is most likely the closest shape of an egg.
What is the measurement of base?
The answer will depend on what measure is required: length of a side, perimeter, radius or diameter (if circular), eccentricity (if an ellipse), area.The answer will depend on what measure is required: length of a side, perimeter, radius or diameter (if circular), eccentricity (if an ellipse), area.The answer will depend on what measure is required: length of a side, perimeter, radius or diameter (if circular), eccentricity (if an ellipse), area.The answer will depend on what measure is required: length of a side, perimeter, radius or diameter (if circular), eccentricity (if an ellipse), area.

What is the perimeter of 38 mm by 28 mm?
The answer will depend on the shape: a rectangle, an ellipse, some other shape?
What is the difference between circumference and perimeter?
Circumference is only used for circles. Perimeter is for every other 2D shape.
What is the distance around a two-dimensional closed figure?
The distance around a 2 dimensional closed figure is its perimeter.

What happens to the sun when the distance increases orbital period of planet?
If a planet's distance from the sun would increase, its revolutionary path would be extended (because it would have to traverse more distance), ergo increasing its period of revolution. Take an ellipse and enlarge it, then measure the perimeter of each ellipse, the larger one will have a larger perimeter.
How do I find the perimeter of an ellipse?
It is approximately 2π√(.5*(a2+b2)) area = πab a= 1/2 height b= 1/2 width
What shape has a perimeter of 14 units?
Any shape you like - a circle, ellipse, triangle, quadrilateral, polygon with n sides, irregular shapes.
What is the perimeter of 16 square centimeters?
There are an infinite number of shapes with an area of 16 square centimetres. The one with the smallest perimeter is a circle of radius 2.2568 cm (to 4 dp). Such a circle will have a perimeter of 14.1796 cm. This value for the perimeter can be increased by changing the circle into an ellipse: making the ellipse flatter and longer (increasing its eccentricity) so that the perimeter increases without changing the area. There is no upper bound to the perimeter. This can also be done for quadrilaterals, with the smallest one being a 4cm x 4cm square. But you could have a rectangle with sides 0.4 cm and 40 cm and a perimeter of 80.8 or 0.04 cm and 400 cm and a perimeter of 800.08 cm or 0.004 cm and 4000 cm and a perimeter of 8000.008 cm and so on - without limit. Or you could have triangles, or polygons with 5 or more sides. The important point is that area does not determine the perimeter.
What is circumference of oval 20 cm X 57 cm?
Minor axis = 20, major axis = 57 Perimeter of ellipse = 128 cms.
Can you make a sentence about circumference?
It seems quite strange that the circumference of the Moon, as observed from the Earth, matches the circumference of the Sun. The perimeter of a circle or of an ellipse is called the circumference.
