The formula for solving the area of a rhombus is :
, where x and y are two intersecting diagonals.
In this case, we are given both values, thankfully. 6 and 7 are to be replaced with x & y. Now, the rest you have to do is simple math.
![(6 * 7) / 2 = 21](https://img.qammunity.org/2021/formulas/mathematics/college/532sjlp9l27pg5bwskdcz9xv7zuo4km820.png)
The area of the rhombus is 21mm.
