Now, I will explain using both area and perimeter.
Now we can infer that the other 6.25 +5 will have the same sum. Therefore we have to solve this:
Which is:
<em>Now</em><em> </em><em>time</em><em> </em><em>to</em><em> </em><em>solve</em><em> </em><em>in</em><em> </em><em>the</em><em> </em><em>area</em><em> </em><em>formula</em><em>.</em>
Length × Width.
First, we're starting by 6.25 × 5.
Which is 62.5.
Either, he had to pay 62.5$ (I doubt it) or he had to pay 22.50$.

I have solved using both formulas, hope this helps, bye!
Julia needs 3 
cups of oatmeal, and she can only get it in cup quantities at a time. We know that 
makes 1 whole, so we need to multiply the amount of whole cups she has by 4.
3 * 4 = 12
Finally, we see that there is cup of extra oatmeal that Julia wants, so we add one more to our sum.
It will take 13 sets of cups of oatmeal to make 3 cups of oatmeal.
Hope that helped =)
3 * 4 = 12
