Answer: 15
Step-by-step explanation:
I think the answer is correct because, The aformula of a parellelogram is base times height. Since we see 5 is the base and 3 is the height all we have to do is multiply 5 times 3 and that equals 15. To make sure we are correct you can divide 15 by 5 or 3 and you would still get a number in the equation.
