Circle:
-- Perimeter ("circumference") = (pi) x (diameter) or (2 pi) x (radius)
-- Area = (pi) x (radius)2 or (1/4 pi) x (diameter)2
Triangle:
-- Perimeter = (length of Side-#1) + (length of Side-#2) + (length of Side-#3)
-- Area = 1/2 (length of triangle's base) x (triangle's height)
Quadrilateral:
Perimeter
-- Any quadrilateral:
(length of Side-#1) + (length of Side-#2) + (length of Side-#3) + (length of Side-#4)
-- Parallelogram, rectangle, or kite: 2 x (length of 1 long side + length of 1 short side)
-- Rhombus or square: 4 x (length of any side)
Area
-- Parallelogram, rhombus, rectangle, square: (length of base) x (height)
-- Rectangle, square: (length) x (width)
-- Square: (length of any side)2
-- Trapezoid: 1/2 (height) x (length of Base-#1 + length of Base-#2)
A square will. The only shape that can enclose more area with the same perimeter is a circle.
The perimeter for a certain area varies, depending on the figure. For example, a circle, different ellipses, a square, different rectangles, and different shapes of triangles, all have different perimeters or circumferences, for the same area.The perimeter for a certain area varies, depending on the figure.

The shape which minimises the perimeter for a fixed area is a circle. A circle of radius 7.334 ft (approx) will have the required area and a perimeter (circumference) of just 46.084 ft. The quadrilateral with the smallest perimeter will be a square with sides of 13 feet: a perimeter of 4*13 = 52 feet. Any regular polygon with more than 4 sides will have a smaller perimeter, for the same area, than a square.
You don't. There is no such thing as the "sum of a quadrilateral". If you mean the perimeter, you add the lengths of the four sides. If you want the area, you can divide the quadrilateral into two triangles, or some other shapes, calculate the individual pieces, and add everything up.
Area of any circle = pi*radius2

If 'R' is the radius of the circle, then-- area of the circle is [ pi R2]-- perimeter of the circle is [ 2 pi R ]
A quadrilateral with area 12 and perimeter 14 is a 4x3cm rectangle.
The perimeter of a circle is its circumference
Area of any circle = pi*radius2

Of a circle,the area is: Pi * r^2,perimeter is: 2* Pi * rWhere, r is the distance from the circle's center to the perimeter, and Pi is a constant: Pi ~ 3.14.
