Find the area of a rhombus if its diagonals are 20mm and 28mm.

In order to solve this problem, you will need some knowledge in the field of geometry, and in particular about rhombuses.

First, let’s write down the rule by which you can find the area of a rhombus through two known diagonals:

The area of a rhombus is half the product of its diagonals:

S = 1/2 * d1 * d2;

d1, d2 – diagonals.

Substitute in the formula:

S = 1/2 * 20 * 28 = 280 mm ^ 2;

Answer; 280 mm ^ 2.
