Hi,

the perimeter of an equilateral triangle is numberically equal to its area. 

Let x represent the length of each 3 sides.

    P = 3x

    A = %281%2F2%29bh+=+%281%2F2%29x+%28xsqrt%283%29%2F2%29+=+%28sqrt%283%29%2F4%29x%5E2

    +3x+=+%28sqrt%283%29%2F4%29x%5E2

     +12%2Fsqrt%283%29+=+x+=+4sqrt%283%29
