I can help your child!
The 'diagonals' of a rhombus are the perpendicular lines that run from one angle to the opposite angle, making a cross in the middle of the shape.
Those diagonals are named P and Q (it doesn't matter which is which). So, the formula is Area=P times Q divided by 2. Let's say the diagnonals were 5" and 6" in length. You would calculate the area as 5x6=30, divided by 2=15 square inches.
I hope that helps!
