Answer:

  • length: 5 ft
  • width: 10 ft

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.
