Hello Jade,
When you have a sentence like "the product of x... and y is z" that means you are MULTIPLYING x by y, and the answer will equal z
Let's apply it to your situation:
- "Product of five and Han’a height" means 5 TIMES Han's height so: 5*h
- "is 60" means = 60
Putting that together you get: 5*h = 60
