Area of an Equilateral Triangle side 9 foot

Steps:

Given that side = 9 ft

Area of an Equilateral Triangle = A = (√3)/4 × 92

Put the value of side in Area Formula.

Area= $(√3)\above 1pt4$ × 92

Area = $(√3)\above 1pt4$ x 9 x 9

Multiply 9.0 ft and 9.0 ft

Area = $(√3)\above 1pt4$ x 81.0

Area = $1.732\above 1pt4$ x 81.0

Area = 0.433 x 81.0

Area= 35.073 ft2

∴ Area of an Equilateral Traingle side 9 ft is 35.073 ft2
