Answer 2

ΔABC का क्षेत्रफल  = $25\sqrt{3}\ cm^2$

चरण-दर-चरण स्पष्टीकरण:

दिया हुआ है ,

एक त्रिभुज ABC में,

AB = BC = CA = 10 cm

or a=b=c= 10cm

हमें हेरॉन  के सिद्धांत का उपयोग करके इसके क्षेत्रफल ज्ञात करना है|

$\bold {Area\ of\ \Delta ABC = \sqrt{s(s-a)(s-b)(s-c)}}$

जहां,s = अर्द्धपरिधि  =$\frac{a+b+c}{2}$

                                          =$\frac{10+10+10}{2}$

                                          =$\frac{30}{2}$

                                       s  = 15 cm

${Area\ of\ \Delta ABC = \sqrt{15(15-10)(15-10)(15-10)}$

                                        = $\sqrt{15(5)(5)(5)}$

                                        =$25\sqrt{3}\ cm^2$

इसलिए,ΔABC का क्षेत्रफल  = $25\sqrt{3}\ cm^2$
