Question

Measure of each side of an equilateral triangle is 12cm. It's area is given by

Answer 1

Answer:

D

Step-by-step explanation:

The area (A) of an equilateral triangle is calculated as

A = $\frac{s^2\sqrt{3} }{4}$ ← s is length of a side

Here s = 12, thus

A = $\frac{12^2\sqrt{3} }{4}$

  = $\frac{144\sqrt{3} }{4}$

  = 36$\sqrt{3}$ → D
