## Area of an Equilateral Traingle side 81 m is 2840.913 m^{2}

**Steps:**

Given that side = 81 m

**Area of an Equilateral Triangle** = A = (√3)/4 × 81^{2}

Put the value of side in Area Formula.

Area= $(√3)\above 1pt4$ × 81^{2}

Area = $(√3)\above 1pt4$ x 81 x 81

Multiply 81.0 m and 81.0 m

Area = $(√3)\above 1pt4$ x 6561.0

Area = $1.732\above 1pt4$ x 6561.0

Area = 0.433 x 6561.0

Area= 2840.913 m^{2}

∴ Area of an Equilateral Traingle side 81 m is 2840.913 m^{2}
