Answer:
(2l + 2w) + (a + b + c)
Step-by-step explanation:
The formula for the perimeter of a rectangle is 
P = 2l + 2w
so if you substitute, it becomes
P = 2(12) + 2(2)
= 24 + 4
= 28
For the perimeter of a triangle the correct formula would be 
P = a + b + c
The missing side in the triangle is 3 because 15 - 12 is 3. 
If you substitute, it becomes
P = 2 + 3 + 6
P = 11
If we add both perimeters together we get the full perimeter of the figure which is 
28 + 11 = 39
I am not sure if you wanted the answer as well but just in case :)

Solution: We are given:
ACT scores follow normal distribution with 
SAT scores follow normal distribution with 
Now, let's find the z score corresponding to Joe's SAT score 1351.

         
         
         
Therefore, Joe's SAT score is 1.56 standard deviations above the mean.
Now, we have find the Joe's ACT score, which will be 1.56 standard deviations above the mean.
Therefore, we have:






Therefore, Joe's equivalent ACT score to SAT score 1351 is 28.4
