(a) 1.732cm
(b) 5.196cm
(c) 0.866cm
(d) 3.496cm
​

Answer 1

Step-by-step explanation:

Given, side of an equilateral triangle is 2√3 cm.

Area of an equilateral triangle = √3/4 (Side)2

= √3/4 (2√3)2 = (√3/4) x 4 x 3

= 3√3 = 3 x 1.732 = 5.196 cm2

Hence, the area of an equilateral triangle is 5.196 cm2.
