Answer:

27.71

Step-by-step explanation:

Using Google, we can find that if we plug in the area, a, the formula for the area of the triangle is [tex]\frac{\sqrt{3} }{4} a^{2}[/tex]. Plugging it in, we get [tex]\frac{\sqrt{3} }{4} * 64[/tex] = 27.71 (approximately)

Area of an equilateral triangle that has sides that are [tex]8[/tex] inches long is equal to [tex]\boldsymbol{16\sqrt{3}}[/tex] square inches

A triangle is a polygon that consists of three sides and three angles.

An equilateral triangle is a triangle in which all sides are equal and all angles are equal.

Length of a side of an equilateral triangle [tex](l)=8[/tex] inches

Area of an equilateral triangle [tex](A)=\boldsymbol{\frac{\sqrt{3}}{4}l^2}[/tex]

                                                        [tex]=[/tex][tex]\boldsymbol{\frac{\sqrt{3}}{4}(8)^2}[/tex]

                                                       [tex]=\boldsymbol{16\sqrt{3}}[/tex] square inches
