Area of an Equilateral Traingle side 81 ft is 2840.913 ft2
Steps:
Given that side = 81 ft
Area of an Equilateral Triangle = A = (√3)/4 × 812
Put the value of side in Area Formula.
Area= $(√3)\above 1pt4$ × 812
Area = $(√3)\above 1pt4$ x 81 x 81
Multiply 81.0 ft and 81.0 ft
Area = $(√3)\above 1pt4$ x 6561.0
Area = $1.732\above 1pt4$ x 6561.0
Area = 0.433 x 6561.0
Area= 2840.913 ft2
∴ Area of an Equilateral Traingle side 81 ft is 2840.913 ft2
