# The perimeter of the football field is 1.6 kilometre. If the width of the field is 200 metres what is the length?

- 800 metres
- 600 metres
- 400 meters
- 200 metres

**Answer: (2) 600 metres **

**Solution:-**

Let the length of the football field be X m.

The perimeters of the football field = 1.6 km = 1,600 m

**Formula-**

**The perimeters of the rectangle = 2 (length + breadth)**

The width of the football = 200 m

Then, 1,600 = 2 (200 + X)

200 + X = 1,600/2

200 + X = 800

X = 800 – 200

X = 600 m

Then, the length of the football is 600 metres.

Hence, the correct answer is option (2) 600 metres.
