Detailed Solution
Download Solution PDFदिलेल्याप्रमाणे:
पहिली बाजू (a) = 4 सेमी
दुसरी बाजू (b) = 5 सेमी
तिसरी बाजू (c) = 7 सेमी
वापरलेले सूत्र:
हेरॉनचे सूत्र
क्षेत्रफळ = √{S × (S - a) × (S - b) × (S - c)}
जिथे, S = (a + b + c)/2
गणना:
S = (4 + 5 + 7)/2 = 16/2 = 8
त्रिकोणाचे क्षेत्रफळ = √{S × (S - a) × (S - b) × (S - c)}
⇒ √{8 × (8 - 4) × (8 - 5) × (8 - 7)}
⇒ √{8 × 4 × 3 × 1}
⇒ √{16 × 6}
⇒ √96 = 4√6 सेमी2
∴ योग्य उत्तर 4√6 सेमी2 आहे.
