## Area of an Equilateral Triangle side 3 centimeters

Steps:

Given that side = 3 cm

Area of an Equilateral Triangle = A = (√3)/4 × 32

Put the value of side in Area Formula.

Area= \$(√3)\above 1pt4\$ × 32

Area = \$(√3)\above 1pt4\$ x 3 x 3

Multiply 3.0 cm and 3.0 cm

Area = \$(√3)\above 1pt4\$ x 9.0

Area = \$1.732\above 1pt4\$ x 9.0

Area = 0.433 x 9.0

Area= 3.897 cm2

∴ Area of an Equilateral Traingle side 3 cm is 3.897 cm2
