I don't want to give you the answer so here is a thorough explanation and an answer if you want it. Set this up as a proportion. Set it up as 5/5=x/12.5. Then multiply 5 by x to get 5x and 12.5 by 5. Once you have this answer, divide it by five to isolate the x. Once you have finished this, you have your answer.
I got the answer 12.5. Make sure you check this so you understand how to solve these kinds of problems.
Median is the middle number
so in this picture median = 5
answer is 5
Answer:
If the dimension increased by doubled, tripled or quadrupled, then it will be 2x, 3x, or 4x for each dimension.
1 is 180 - 2(68) = 180 - 136 = 44
2 is
5x + 12 + 3x + 8 = 180
8x + 20 = 180
8x = 160
x = 20
