Answer:
Step-by-step explanation:
Height of the equilateral triangle = [tex]\frac{\sqrt{3} }{2}[/tex] * side = [tex]\frac{\sqrt{3} }{2}[/tex] *10 = [tex]5\sqrt{3}[/tex]
Area of an equilateral triangle = [tex]\frac{\sqrt{3} s^{2} }{4}[/tex] = [tex]\frac{\sqrt{3} 10^{2} }{4}[/tex] = [tex]\frac{100\sqrt{3}}{4}[/tex] = [tex]25\sqrt{3}[/tex]
