The bases of an isosceles trapezoid are 14 cm and 18 cm, and its diagonals are perpendicular. Find the height of the trapezoid.

Since this is an isosceles trapezoid, the height can be calculated faster without additional constructions and calculations.
In this case, the height will be equal to the half-sum of the bases (just this is given to us in the condition)
h = (a + b) / 2 = (14 + 18) / 2 = 16 cm
Answer: 16 cm.
