Exploring the geometry of quadrilaterals, this overview discusses how to calculate their perimeter and area. It covers formulas for squares, rectangles, parallelograms, trapezoids, rhombuses, and kites. Understanding these calculations is essential for real-world applications like construction and landscaping, where precise measurements are crucial. The use of the distance formula in coordinate geometry is also highlighted for determining these dimensions on a Cartesian plane.

Quadrilaterals are polygons with four sides
Square
The perimeter of a square is four times the length of one side, and the area is the length of one side squared
Rectangle
The perimeter of a rectangle is the sum of all sides, and the area is the product of its length and width
Parallelogram
The perimeter of a parallelogram is the sum of twice each of the adjacent sides, and the area is the product of its base and the perpendicular height
Trapezoid
The perimeter of a trapezoid is the sum of the lengths of all sides, and the area is the average of the lengths of the two parallel sides multiplied by the height
Rhombus
The perimeter of a rhombus is the sum of the lengths of all sides, and the area is half the product of the lengths of the diagonals
Kite
The perimeter of a kite is the sum of the lengths of all sides, and the area is half the product of the lengths of the diagonals
Perimeter and area calculations are used in practical applications such as determining the amount of fence needed for a yard or the amount of grass seed required
