Find the area of a rhombus if its diagonals are 20 and 6.

Given:

rhombus ABCE,

AC and BE – diagonals, BE = 20;

AC = 6.

Find the area of the rhombus ABCE, that is, S ABCE -?

Solution:

Consider a rhombus ABCE. The area of a rhombus is equal to the product of 1/2 on its diagonal.

Therefore, the area of the rhombus ABCE, that is, S ABCE = 1/2 * AC * BE;

S ABCE = 1/2 * 20 * 6;

S ABCE = (1 * 20 * 6) / 2;

S ABCE = (1 * 10 * 6) / 1;

S ABCE = 60.

Answer: S ABCE = 60.
