Question

what is the area of an equilateral triangle with side
$3 \sqrt{2}$
​

Answer 1

As we know that ==>

Area of equilateral triangle is

$\frac{ \sqrt{3} }{4} {s}^{2}$

Side of triangle = 3√2

putting the value of side in the above mentioned formula.

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

9√3 unit ²

Answer 2

GIVEN :

Side of an Equilateral triangle = $3 \sqrt{2}$

Area of the triangle = ?

We know that,

Area of equilateral triangle = (√3/4)a²

= (√3/4)a²

= (√3/4) × (3√2)²

= (√3/4) × 9 × 2

= √3/4 × 18

= 18√3 / 4

Therefore, the area of traingle is (18√3)/4.

Equilateral Triangle : An equilateral triangle is a triangle whose three sides are equal.

The perimeter of Equilateral triangle is 3 × sides.
