The area of the trapezoid through the midline is expressed by the following formula:
S = lh, where l is the middle line of the trapezoid, h is its height. It follows from this formula that
l = S / h.
According to the condition of the problem, the height of the trapezoid is 20 cm, its area is 500 cm square, substituting this data into the formula, we calculate:
l = 500/20 = 25 (cm)
Answer: 25 cm
