Find the area of a rhombus if its diagonals are 20 and 10.

The diagonals of the rhombus divide it into four equally great triangles, then Savsd = 4 * Savo.

The diagonals at the intersection point are divided in half, then AO = AC / 2 = 20/2 = 10 cm, BO = BD / 2 = 10/2 = 5 m.

Savo = AO * BO / 2 = 10 * 5/2 = 25 cm2.

Savsd = 25 * 4 = 100 cm2.

Answer: The area of the rhombus is 100 cm2.
