Consider a triangle with one side measuring 20/9 centimeters (cm) with all the same length. If all sides of a pentagon, which has the same perimeter as this triangle, have the same length, what is the length of one side?
20/9 3 [OP_MUL] 5 [OP_DIV]
var_a = 2.2222222222222223
var_b = 3
var_c = var_a * var_b
var_d = 5
var_e = var_c / var_d
print('{:.2f}'.format(round(var_e+1e-10,2)))
