I painted a trapezoidal roof. The upper side of the roof is 3.4 centimeters (cm) longer than the lower side, the height is 5.2 centimeters (cm) and the area is 100.62 square centimeters (cm2). How many centimeters (cm) is the length of the lower side of the roof?
100.62 2 [OP_MUL] 5.2 [OP_DIV] 3.4 [OP_SUB] 2 [OP_DIV]
var_a = 100.62
var_b = 2
var_c = var_a * var_b
var_d = 5.2
var_e = var_c / var_d
var_f = 3.4
var_g = var_e - var_f
var_h = 2
var_i = var_g / var_h
print('{:.2f}'.format(round(var_i+1e-10,2)))
