Question

Lena is building a fence around her rectangular flower garden. The width is twice the length. The perimeter of the garden is 30 ft. What are the length and width of the garden?

Answer 1

Answer:

• length: 5 ft
• width: 10 ft

Step-by-step 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.
