The area of an equilateral triangle is cm2. Its perimeter is –
It is given in the question that,
Area of an equilateral triangle = 36 cm2
We know that,
Area of an equilateral triangle =
36 =
(Side)2 =
Side = 12 cm
∴ Perimeter of equilateral triangle = 3 × Side
= 3 × 12
= 36 cm
Hence, option (a) is correct
