I painted a trapezoid on drawing paper. The lower side is 3.6 centimeters (cm) shorter than the upper side, the height is 5.2 centimeters (cm), and the area of the roof is 96.98 square cm (cm2). How many centimeters (cm) is the lower edge of this trapezoid?
96.98 2 [OP_MUL] 5.2 [OP_DIV] 3.6 [OP_SUB] 2 [OP_DIV]
var_a = 96.98
var_b = 2
var_c = var_a * var_b
var_d = 5.2
var_e = var_c / var_d
var_f = 3.6
var_g = var_e - var_f
var_h = 2
var_i = var_g / var_h
print('{:.2f}'.format(round(var_i+1e-10,2)))
