त्रिकोणाचा अंतःवृत्त त्रिज्या 8 सेमी आहे आणि त्याच्या बाजूंच्या लांबींची बेरीज 125 सेमी आहे.
वापरलेले सूत्र:
क्षेत्रफळ (A) = अंतःवृत्त त्रिज्या (r) × अर्धपरिघ (s)
जिथे, अर्धपरिघ (s) = (बाजूंच्या लांबींची बेरीज) / 2
गणना:
s = 125 / 2
⇒ s = 62.5 सेमी
A = r × s
A = 8 × 62.5
⇒ A = 500 सेमी2
∴ योग्य उत्तर पर्याय (3) आहे.
