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)
What is the difference between finding the perimeter of a polygon and finding the area of a polygon?
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.
Is the formula for finding the area of an oval the same as the formula for finding the area of a circle?
No because the formula for finding the area of an oval, which is an ellipse, is quite different
What is the formula for finding the perimeter of a square that has an area of 144 square inches?
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.
What is the rule for finding the area and perimeter of a parallelogram?
area of parallelogram= base*height perimeter= 2(length+breadth)
What is the formula for finding the area of a regular polygon with perimeter P and apothegm length a?
Area of regular polygon: 0.5*apothem*perimeter
What is the formula for finding a parrellagram?
The area of a Parallelogram is Base * Height The Perimeter is 2(side1 + side2)
What is the formula for finding the area of a quadrangular prism?
A = 2AB + AL AB = area of the base AL = lateral area = Perimeter X height
What is the formula for finding surface area of a trapezoidal prism?
Perimeter = area + b1 + b2 + c P = a + b1 + b2 + c
What is the formula for finding the area of a regular polygon with perimeter P and apothem length a?
A = (1/2)Pa A being the area, P being the perimeter of the regular polygon, and the apothem length being a.
What is the formula for finding the area and perimeter of a square?
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

How do you find an apothem?
The formula for finding an apothem is s = 1/2 aP. S is the area, a is the apothem, and P is the perimeter.

What is the formula of the area and perimeter of a triangle?
Area = 0.5 x base x height Perimeter = side 1 + side 2 + side 3 Formula for Area of a triangle is A = bh/2, where A is Area, b is base, and h is heigth. Formula for finding the perimeter is P = s1 + s2 + s3, where s represent side, or P = AB + BC + AC where the letters represent the sides.
