Question

Find the area of an equilateral triangle whose each side is 12 cm​

Answer 1

Answer:

36root3

Step-by-step explanation:

1. area of equilateral triangle=root3/4×a²

=root3/4×12²

=36root3

Answer 2

To find the area of an equilateral triangle, the formula we will use is:

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

where, a is the side of the triangle.

Given: side = a = 12cm

Area-

= root3/4 × (12)^2

=root3/4 × 144

=root3/ × 36

= $36 \sqrt{3}$

Hence, the area of the triangle is $36 \sqrt{3} cm^{2}$
