Geometric Area Calculations and Formulas

Area Formulas and Definitions

• Rectangle or Parallelogram area: $A = b \times h$
• Square area formula: $A = s^2$
• General calculation for area: $A = b \times h$
• Trapezoid or complex area notation: $A = \frac{1}{2} \times (b_1 + b_2) \times h$

Mathematical Calculations

• Calculation involving decimals: $1.6 \times 8.2 = 13.12$
• Calculation result: $31.185$
• Value: $10.875$
• Arithmetic sequence for area addition:     * $10 \times 6 = 60$     * $6 \times 4 = 24$     * Summation: $60 + 24 = 84$
• Other recorded numerical values: $12$, $45$, $122$, $20$, $3.3$, $64$, $847.40$, and the notation $64:78=3$
