Area of an Equilateral Traingle side 21 ft is 190.953 ft2
Steps:
Given that side = 21 ft
Area of an Equilateral Triangle = A = (√3)/4 × 212
Put the value of side in Area Formula.
Area= $(√3)\above 1pt4$ × 212
Area = $(√3)\above 1pt4$ x 21 x 21
Multiply 21.0 ft and 21.0 ft
Area = $(√3)\above 1pt4$ x 441.0
Area = $1.732\above 1pt4$ x 441.0
Area = 0.433 x 441.0
Area= 190.953 ft2
∴ Area of an Equilateral Traingle side 21 ft is 190.953 ft2
