Perimeter of Geometric Figures
The perimeter of a geometric figure is the total distance around the figure. For example, the perimeter of a rectangle is calculated by adding the lengths of all four sides. The formula for the perimeter (P) of a rectangle is P = 2(l + w), where l is the length and w is the width.
Area of Geometric Figures
The area of a geometric figure is the amount of space enclosed within its boundaries. The area of a rectangle is calculated by multiplying its length by its width (A = l × w). For a triangle, the area is calculated using the formula A = 1/2 × base × height.
Volume of Geometric Figures
Volume measures the three-dimensional space occupied by an object. For a rectangular prism, the volume is calculated by multiplying its length, width, and height (V = l × w × h). For a cylinder, the volume is calculated using the formula V = πr²h, where r is the radius and h is the height.
