Hi, your answer should be B. Please tell me if I am wrong, I hate to mess people up.
They are about 141.42 feet away from the welcome center
The answer is 68.
Field had shape of rectangle since has difference in length and width. The perimeter of rectangle can be expressed as:
P = 2 × (a + b)
If:
a = 100 m
b = 70 m
Then
P = 2 × (100 m + 70 m)
P = 2 × 170 m
P = 340 m.
If posts are on every 5 m, the number of needed posts is:
340 m ÷ 5 m = 68.
Thus, 68 posts are needed for the fence.
Hope that helps.Have a nice day!! ^^
