In an isosceles trapezoid, the midline is 10 cm, and the diagonals are mutually perpendicular. Then the area of the trapezoid is.

If in an isosceles trapezoid the diagonals intersect at right angles, and the length of the midline of the trapezoid is 10 cm, then the area of the trapezoid is equal to the square of the midline, since the height of such a trapezoid is equal to the midline.

Answer: The area of the trapezoid is 100 cm2.
