Answer
The total distance that Jane covers is
8 (l + w)
Explanation
We are told that every morning, Jane runs 4 laps around a rectangular garden with length l, and width w.
The perimeter of a rectangle is given as
Perimeter = 2 (l + w)
So, in 1 lap where Jane runs round the garden, she covers a full perimeter of the garden.
1 lap = 2 (l + w)
In 4 laps, she would cover
4 laps = 4 × 2 (l + w)
= 8 (l + w)
Hope this Helps!!!
