Height of equilateral triangle = root3 × side of equilateral triangle / 2
=> root3 = root3 a/2
=> a = 2
Length of side = 2 unit
Area = root3 a^2 /4
= root3 × 2 × 2 / 4
= root3 sq. unit.
Perimeter = 3 × length of side
= 3 × 2
= 6 cm
=> root3 = root3 a/2
=> a = 2
Length of side = 2 unit
Area = root3 a^2 /4
= root3 × 2 × 2 / 4
= root3 sq. unit.
Perimeter = 3 × length of side
= 3 × 2
= 6 cm
