त्रिभुज के शीर्ष = (1,2), (-4,-3), (4,1)
प्रयुक्त सूत्र:
त्रिभुज का क्षेत्रफल = ½ [x1 (y2 - y3) + x2 (y3 - y1) + x3 (y1 - y2)]
जिनके शीर्ष (x1, y1), (x2, y2) और (x3, y3) हैं
गणना :
⇒ त्रिभुज का क्षेत्रफल = (1/2) × [1(-3 – 1) + (-4) (1 – 2) + 4{2 – (-3)}]
= (1/2) × {(-4) + 4 + 20}
= 20/2
= 10 वर्ग इकाई
