மூலைவிட்டங்கள் \(10\text{ செ.மீ}\) மற்றும் \(12\text{ செ.மீ}\) அளவு கொண்ட சாய்சதுரத்தின் பரப்பளவு காண்க:
💡 Explanation:
- Formula: The area of a rhombus with diagonals \(d_1\) and \(d_2\) is: \[\text{Area} = \frac{1}{2} \times d_1 \times d_2\]
- Given: \(d_1 = 10\text{ cm}\), \(d_2 = 12\text{ cm}\)
- Calculation: \[\text{Area} = \frac{1}{2} \times 10 \times 12 = 5 \times 12 = \mathbf{60\text{
