Enter the Equilateral Triangle Side


Area of an Equilateral Triangle side 81 foot is 2840.913 foot2.

An equilateral triangle has all its sides as equal. The perpendicular drawn from the vertex of the triangle to the base divides the base into two equal parts. To calculate the area of the equilateral triangle, we have to know the measurement of its sides.Area of an Equilateral Triangle side 81 foot is 2840.913 foot2.

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
