Answer:
2 miles
Explanation:
Width, W = 1 mi.
Length = L
Perimeter, P = 6 mi.
2L + 2W = P:
2L + 2(1) = 6
2L + 2 = 6
2L = 6 - 2
2L = 4
L = 4 / 2
L = 2
Answer: 2 miles
If this is wrong then sorry!
Hope it help!
Let's call the length x. Since perimeter = 2 * (length + width) we can write:
6 = 2(x + 1/2)
3 = x + 1/2
x = 2 and 1/2
The answer is 2 and 1/2 miles long.
