Area of an Equilateral Triangle side 9 inches

Steps:

Given that side = 9 in

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 in and 9.0 in

Area = $(√3)\above 1pt4$ x 81.0

Area = $1.732\above 1pt4$ x 81.0

Area = 0.433 x 81.0

Area= 35.073 in2

∴ Area of an Equilateral Traingle side 9 in is 35.073 in2
