A triangle with sides 5cm, 12cm, and 13 cm has an inradius of 2 cm. What is its area?
5सेमी, 12 सेमी और 13 सेमी भुजाओं वाले एक त्रिभुज की अन्तः त्रिज्याः 2 सेमी है। इसका क्षेत्रफल क्या हैं?
Detailed Solution & Logic
Correct Answer:
30 cm\(^2\)
Semi-perimeter $ s=\dfrac{5+12+13}{2}=15 $
Area of triangle= $ r\times s $
Area = $ 2\times 15=30 \text{cm}^2 $
