[ Answer ]
[ Explanation ]
The Median Is The Number That Separates Top Half Of The Number Set From The Bottom
Ex: 1, 1, 2, 5, 6, 6, 9
Median - 5
Explanation: 5 is the number in the exact middle that is separating the bottom half of the number set (1, 1, 2) from the top half of the number set (6, 6, 9).
Ex: 1, 1, 2, 6, 6, 9
Median - 4
Explanation: 4 is the mean of 2 and 6. (Mean = Sum / Numbers you are adding up)
===========================
22, 37, 49, 15, 72
Order numbers from least to greatest:
15, 22, 37, 49, 72
37 is the mean because it is in the exact middle and separates 15 and 22 from 49 and 72.

Answer:56.8 inches
Step-by-step explanation:
For perimeter we must find the lengths of the 2 diagonal sides of the triangle which are the same because it is isosceles.
the triangle is cut directly in half so both halves of the base are 17/2
17/2 = 8.5
solve through pythagoren theorum
altitude^2 + (half of base)^2 = (diagonal length)^2
18^2 + (8.5)^2 = (diagonal length)^2
324 + 72.25 = (diagonal length)^2
396.3 = (diagonal length)^2
= diagonal length
diagonal length = 19.9
diagonal length + diagonal length + base = perimeter
19.9 + 19.9 + 17 = perimeter
56.8 inches = perimeter
