Answer 1

Answer:

5348 metres

Explanation:

Given that,

Area of a runway is 49.48 hectare

And it's width is 200metres

We need to find its perimeter.

Perimeter of the runway is given by :

= 2(l + w)

Where,

• ‘l’ denotes the length
• And ‘w’ denotes the width of the runway.

Finding it's lenght

Since, area = lenght × width

∴ Length = area ÷ width

Where,

• Area is 49.48 hectare converting in metres we'll get 494800 metres²
• And, width is 200 metres

= 494800 ÷ 200

= 2474 metres

Now, calculating it's perimeter :-

= 2(l + w)

= 2(2474 + 200)

= 5348 metres

∴ Perimeter of a runway is 5348 metres
