Question

Side of an equilateral triangle is 4cm. Its area is
a) 4/3 cm^2 (b) √3/4cm^2
(C)√3cm^2
(d) 2√3cm^2

Pls answer tha above question quickly! : )​

Answer 1

area of equilateral triangle = √3/4×s^2

= √3/4×4^2

= √3/4×16

= √3×4

= 4√3 cm^2

Answer 2

Answer:

$4\sqrt{3} cm^2$

Step-by-step explanation:

We know,

Area of equilateral triangle = $\frac{\sqrt{3} }{4}$ x $(side)^{2}$

                                             = $\frac{\sqrt{3} }{4}$ x $4^{2}$

                                             = $\frac{\sqrt{3} }{4}$ x 16

                                             = $4\sqrt{3}$
