एक समचतुर्भुज के दो विकर्णों की लंबाई 20 cm और 23 cm हैं। समचतुर्भुज का क्षेत्रफल (cm $^2$) क्या होगा ?

460 345 115 230

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
