| The non-parallel sides of the trapezoid are its lateral sides. Knowing the perimeter of the trapezoid and the sum of the lengths of the sides, we can find the sum of the lengths of the bases:

245 – 157 = 88.

The length of the midline of the trapezoid is half the sum of the lengths of the bases, which means:

m = 88/2 = 44.
