Question

The area of an equilateral triangle with side 3 root 2 cm​

Answer 1

Answer:

$15.6 \: {cm}^{2}$

Step-by-step explanation:

Given:

$side = 3 \sqrt{2} cm$

$area = \frac{ \sqrt{3} }{4} \times {side}^{2}$

$= \frac{ \sqrt{3} }{2} \times {(3 \sqrt{2} )}^{2}$

$= \frac{ \sqrt{3} }{2} \times 18$

$= 9 \sqrt{3} = 15.6 \: {cm}^{2}$

Answer 2

$\huge\underline\mathrm{Solution-}$

Area of an equilateral Δ :

$\frac{ \sqrt{3} }{4} \times {side}^{2}$

$= \frac{ \sqrt{3} }{4} \times {(3 \sqrt{2} )}^{2}$

$= \frac{ \sqrt{3} }{4} \times 18$

$\huge\underline\mathrm{Answer-}$

Area of the Δ is 15.6 cm^2
