Question

The perimeter of an equilateral triangle is 1360m. what is its area?​

Answer 1

Answer:

88988.92m²

Step-by-step explanation:

A = √3/4a²

P=3a

Solving for A

A =√3P²/36 = √3.1360²/36 =88988.92149m²

Answer 2

Answer:

177576$m^{2}$

Step-by-step explanation:

We must know that the lengths of an equilateral triangle are all equal.

So, length:

1360m/3

=453.3...

≈453m

The formula to find the area of an equilateral triangle is:

Let h be the height and a be the length.

h=a*$\sqrt{3}$/2

So,

Height:

453m*$\sqrt{3}$/2

=392.3095...m

≈392m

So, area:

(453*392)m

=177576$m^{2}$ (approximately)
