Answer:
18.
Step-by-step explanation:
If the equation for the area of a rhombus is A=pq÷2, then you take 72, and you multiply it by 2, which gets you 144, then you simply take 144 and divide it by 8, which gets you 18. And then once you've done all that, you can simply check your math by plugging the numbers into the equation formula I've provided above. In case you're unsure of what it is, here it is again, A=pq÷2.
