Step-by-step explanation:
Perimeter of Equilateral Triangles
Since equilateral triangles have three equal sides, P = 3 × a P = 3 × a , or P = 3a P = 3 a , where P is perimeter and a is the length of any side.
The length of the equilateral triangle's side is the length of the hypotenuse of the 30-60-90. Using this ratio, we find that the length of this triangle's hypotenuse is 4. Thus the perimeter of the equilateral triangle will be 4 multiplied by 3, which is 12.
