Area of a Circle:

pi X r2

Where "r" is the radius.

Perimeter of a Circle:

2 X pi X r

OR

pi X d

Where "r" is the radius and "d" is the diameter.

Do you mean "perimeter" and "Area"? If so, if you are finding the perimeter of a figure, you take the lengths of all of the sides and add them up. If you are finding area, the method of which you find the area of the figure depends on what the figure is. For quadrilaterals, the formula is: A=lw.(Area=length times width) For triangles, the formula is: A=1/2lw. (Area=One half length times width)

Finding the perimeter of a polygon is finding how far it is in total along all the edges of the polygon; whereas finding the area of a polygon is finding how much space the polygon covers. The perimeter of a polygon forms the boundary around the area of the polygon.

No because the formula for finding the area of an oval, which is an ellipse, is quite different

The formula for the area (A) of a square is A = L2 where L is the side length of the square. Therefore L = √A. The formula for the perimeter (P) of a square is P = 4L : as L = √A, then P = 4√A When A = 144, then P = 4 √144 = 4 x 12 = 48.

Area of regular polygon: 0.5*apothem*perimeter

The area of a Parallelogram is Base * Height The Perimeter is 2(side1 + side2)

A = 2AB + AL AB = area of the base AL = lateral area = Perimeter X height

Perimeter = area + b1 + b2 + c P = a + b1 + b2 + c

A = (1/2)Pa A being the area, P being the perimeter of the regular polygon, and the apothem length being a.

The area of a square is: A = Width × Height or A = Length * Length = Length^2 The Perimeter of a square is: P = Length + Length + Length + Length = 4 * Length
