Finding the Midline of a Trapezoid

To find the midline of a trapezoid, we need to determine the length of the smaller base and the larger base. From the given information, we know that the larger base is divided into two segments, with the larger segment measuring 22 cm. Let's calculate the length of the smaller base and then find the midline.

Let's assume that the length of the smaller base is 'x' cm. Since the larger segment is given as 22 cm, the length of the smaller segment can be calculated as the difference between the larger segment and the length of the smaller base:

Length of smaller segment = Length of larger segment - Length of smaller base

22 cm = x cm + Length of smaller base

Simplifying the equation, we get:

Length of smaller base = 22 cm - x cm

Now, to find the midline of the trapezoid, we need to calculate the average of the lengths of the two bases. The midline is the line connecting the midpoints of the two bases.

Midline = (Length of smaller base + Length of larger base) / 2

Substituting the values, we get:

Midline = (22 cm - x cm + x cm) / 2

Simplifying the equation, we get:

Midline = 22 cm / 2

Therefore, the midline of the trapezoid is 11 cm.

Please note that the given information does not provide the exact lengths of the bases or any other measurements. The calculation is based on the assumption that the larger segment of the base is 22 cm.
