Answer:
The wall built around the field is 160 meters.
Step-by-step explanation:
Given that a square field is 40m long, to determine what is the length of wall which is constructed around it, the following calculation must be performed:
40 x 4 = X
160 = X
Therefore, the wall built around the field is 160 meters.

Just calculate this:
A) 2(3m + 5) = 6m + 10 - incorrect
B) -2(5 - 3m) = -10 + 6m - could be correct
C) 2(3m - 10) = 63 - 20 - incorrect
So <u>the correct answer has to be B</u>: -10 + 6m is the same as 6m - 10.
