Answer:
Option B : [tex]6.25\sqrt{3}[/tex] square inches.
Step-by-step explanation:
The area of an equilateral triangle is given by :
A = [tex]\frac{\sqrt{3}}{4}a^{2}[/tex]
Where, a is the side of the triangle.
Here in the question, we have been given the side of the triangle as 5 inches.
So, area is : [tex]\frac{\sqrt{3}}{4}\times5^{2}[/tex]
Simplifying this we get, [tex]\sqrt{3}\times\frac{25}{4}[/tex]
Area = [tex]6.25\sqrt{3}[/tex] square inches.
