Hello!
The answer is:
The area of the rhombus is equal to 64 squared inches.

Why?
Since we already know half of the length of the diagonals of the rhombus, we can calculate the area of the rhombus using the following formula:

From the image we can see that:


So, substituting, we have:

Hence, we have that the area of the rhombus is equal to 64 square inches.
Have a nice day!
