You can put this solution on YOUR website!
in a 30-60-90 triangle the legs are x & xsqrt3
the hypotenuse = 2x
..
Area = !/2 * base * height
Area+=+1%2F2+%2A+x%2Ax%2Asqrt%283%29
+24+sqrt%283%29=+1%2F2%2Ax%2Ax%2Asqrt%283%29
multiply by 2
48sqrt%283%29=x%5E2%2Asqrt%283%29
divide by sqrt3
x^2= 48
x = 6.92
hypotenuse = 2*6.92= 13.84
second leg = x sqrt*(3)
=6.92*sqrt*(3)
= 11.98
..
perimeter = 11.98+6.92+13.84= 32.74
