Answer 1

Answer:

Option B. $25\sqrt{3}$ $cm^{2}$ .

Step-by-step explanation:

We are given that each side of equilateral triangle is 10 cm.

Area of equilateral triangle = $\frac{\sqrt{3} }{4}* side^{2}$

                                             =  $\frac{\sqrt{3} }{4}* 10^{2}$ = $\frac{\sqrt{3} }{4}* 100$

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

Therefore, area of an equilateral triangle is $25\sqrt{3} cm^{2}$ .
