A triangle has vertices of point A, point B, and point C. In this case, the length of side AB is 4.9 centimeters (cm), and the area of this triangle is 9.31 square centimeters (cm2). If a line is drawn perpendicular to side AB from point C and D is the point where it intersects, how many centimeters (cm) is the length of the line segment CD?
9.31 2 [OP_MUL] 4.9 [OP_DIV]
var_a = 9.31
var_b = 2
var_c = var_a * var_b
var_d = 4.9
var_e = var_c / var_d
print('{:.2f}'.format(round(var_e+1e-10,2)))
