The side of the rhombus is 6 and the acute angle is 30 degrees. What is the product of its diagonals?

Let’s define the area of a rhombus through the length of its sides and the angle between them.

Savsd = AB * AD * Sin30 = 6 * 6 * (1/2) = 18 cm2.

Let’s define the area of a rhombus through the lengths of its diagonals.

Savsd = АС * ВD / 2.

AC * BD = 2 * Savsd = 2 * 18 = 36.

Answer: The product of the lengths of the diagonals is 36.
