The width of the field is 250 meters, the length is 2 times the size of the field.

Think like this: the field is shaped like a rectangle. We know that the field is 250 meters wide and twice as long. We need to find the area.
First, let’s find the length of the field.
1) 250 * 2 = 500 meters – the length of the rectangle.
If we know the width and length of the rectangle, then we can find the area. The area is the length of the rectangle multiplied by the width.
2) 500 * 250 = 125,000 square meters.
Answer. The field area is 125,000 square meters.
