Letâ€™s assume the width of the field is x meters.

The perimeter of a rectangle is given by the formula: P = 2L + 2W, where P is the perimeter, L is the length, and W is the width.

In this case, we have: 700 = 2(240) + 2x Simplifying the equation, we get: 700 = 480 + 2x Subtracting 480 from both sides, we get: 220 = 2x Dividing both sides by 2, we get: x = 110

So, the width of the field is 110 meters.

The area of a rectangle is given by the formula: A = L * W, where A is the area, L is the length, and W is the width.

In this case, we have: A = 240 * 110 Calculating the area, we get: A = 26,400 square meters

To convert square meters to hectares, we divide by 10,000 (since 1 hectare = 10,000 square meters).

So, the area of the field is: 26,400 / 10,000 = 2.64 hectares.
