D and B are both the answers
The perimeter is the measure around the shape, so just add all the sides together-
6+5x+x+2
6x+8
Since this is a right triangle, you multiply the legs (6 and x+2) and divide by 2
6(x+2)
6x+12
/2
3x+6

Answer: 5 cakes</h3>
================================================
Explanation:
Let's start off converting the mixed number 12 & 1/4 to an improper fraction.

Do the same for the other mixed number 2 & 1/3.

-----------------------
From here, we divide the two fractions. I converted them to improper fractions to make the division process easier.

The last step is to convert that result to a mixed number.

Note that 21/4 = 5.25 and 1/4 = 0.25 to help check the answer.
-----------------------
Therefore, she can make 5 cakes. The fractional portion 1/4 is ignored since we're only considering whole cakes rather than partial ones.
