Answer:
The area of the square is 121mm
Explanation:
To solve this we need two basic formulas:
P = 4s
A =

P = perimeter
s = the length of the side
Since the shape is a square all the sides are the same length. To get the value of 's' we need to isolate:
P = 4s
44 = 4s
44 / 4 = 4s / 4
11 = s
Now plug in the answer for 's' to get the area:
A =

A =

A = 121
Hope this helps.
