To determine the correct drawing for a rectangle that has a scale of 1 box = 20 meters, we first need to convert the dimensions of the original rectangle, which is 8 units long and 4 units wide under a scale of 1 box = 5 meters.

  1. Find the actual dimensions in meters:

    • Length: 8 units * 5 meters/unit = 40 meters
    • Width: 4 units * 5 meters/unit = 20 meters

  2. Convert these dimensions for the new scale (1 box = 20 meters):

    • Length in boxes: 40 meters / 20 meters/box = 2 boxes
    • Width in boxes: 20 meters / 20 meters/box = 1 box

So, under the new scale of 1 box = 20 meters, the rectangle should measure 2 units long and 1 unit wide.

Now, looking at the provided options, the drawing that matches this measurement is:

  • Image with alt text: A grid is shown with a rectangle drawn on it. The rectangle is 2 units long and 1 unit wide, labeled with 2 and 1 respectively. Scale: 1 box = 20 meters.

This is the correct option.
