Triangle and Rectangle Formulas
- Area of a Triangle: Calculated using the formula A = 1/2bh, where b represents the base and h represents the height.
- Perimeter of a Rectangle: Determined with the formula P = 2L + 2W, where L is the length and W is the width.
Circle and Square Formulas
- Area of a Circle: Given by the formula A = πr², with r being the radius and π approximately equal to 3.14159.
- Perimeter of a Square: Calculated using P = 4s, where s symbolizes the length of one side.
Interest Calculation
- Simple Interest: Computed with I = Prt, where I is the interest, P is the principal amount, r is the rate of interest per time period, and t is the time the money is invested or borrowed.
