The area of an equilateral triangle 
is 
. What is the perimeter of 
?
The area of an equilateral triangle
The area is given, which will allow us to calculate the side of the triangle and hence we can also find the perimeter.
The area for an equilateral triangle is given by the formula
, where 
is the length of the side of the triangle.
Therefore, 
, where 
is the area.
Thus 
, and the perimeter of an equilateral triangle is three times the side, hence, the final answer is 
.

The trick to this one is to carefully put together what you are given.
We know that two of our angles are equal to 60 degrees. This means that the last angle is also 60 degrees. This make HFT an equilateral triangle.
Equilateral triangles always have equal sides and equal angles, so our last side has to be 7 light years as well.
