समबाहु त्रिभुज की ऊँचाई = 9√3
प्रयुक्त सूत्र:
ऊँचाई = a√3 / 2
क्षेत्रफल = a2√3 / 4
गणना:
सूत्र के अनुसार,
⇒ ऊँचाई = a√3 / 2
⇒ 9√3 = a√3 / 2
⇒ a = 18 सेमी
अब त्रिभुज का क्षेत्रफल,
⇒ क्षेत्रफल = a2 √3 / 4
⇒ क्षेत्र = \(\frac{18 \times 18 \times \sqrt3}{4}\)
⇒ क्षेत्रफल = 81√3 सेमी2
⇒ अतः, समबाहु त्रिभुज का क्षेत्रफल 81√3 सेमी2 है।
