The lengths of the two diagonals
The lengths of the two diagonals of a rhombus are 20 cm and 23 cm. What is the area (in cm\(^2\) ) of the rhombus?
एक समचतुर्भुज के दो विकर्णों की लंबाई 20 cm और 23 cm हैं। समचतुर्भुज का क्षेत्रफल (cm \(^2\)) क्या होगा ?
Detailed Solution & Logic
Correct Answer:
230
$ \text{Area of a rhombus} = \frac{1}{2} d_1 d_2 $
$ d_1 = 20 \text{ cm},; d_2 = 23 \text{ cm} $
Area = $ \frac{1}{2} \times 20 \times 23 $
$ = 10 \times 23 $
$ = 230 \text{ cm}^2 $
Answer = 230
