inches
GPT 3.5
To find the width of the picnic area in the drawing, we can set up a proportion using the scale. The ratio of the width in the drawing to the width in real life is 1 inch : 4 yards.

Let x be the width of the picnic area in the drawing in inches.
Then, we have the proportion: x/80 yards = 1 inch/4 yards.

To solve for x, we can cross multiply:
80 yards * 1 inch = x * 4 yards.

Simplifying the right side:
80 inches = 4x.

Dividing both sides by 4:
20 inches = x.

Therefore, the width of the picnic area in the drawing is 20 inches.
