(x1 ,y1) = (2, 4),
(x2,y2) = (-3, -1)
(x3 ,y3)= (5, 3)
प्रयुक्त सूत्र:
त्रिभुज का क्षेत्रफल = [x1(y2 – y3) + x2(y3 – y1) + x3(y1 – y2)]/2
गणना:
त्रिभुज का क्षेत्रफल = [x1(y2 – y3) + x2(y3 – y1) + x3(y1 – y2)]/2
सूत्र में मानों को प्रतिस्थापित करने पर,
⇒ [2(-1 – 3) + (-3)(3 – 4) + 5(4 + 1)]/2
⇒ [-8 + 3 + 25]/2 = 10 वर्ग ईकाई
