Answer:
Explanation:
The formula for the perimeter is ...
P = 2(L +W)
We are also told the relation between length and width:
W = 2L
Using these formulas with the given value of perimeter, we have ...
30 = 2(L +2L)
30 = 6L . . . . . . . simplify
5 = L . . . . . . . . divide by 6
W = 2(5) = 10 . . . find W using the value of L
The garden is 5 feet long and 10 feet wide.
