Question

the area of asquare field is 2.25 hectares.find its perimeter in metres if hectare is qual to 10000square metres​

Answer 1

Perimeter of the square field is 600 meters.

Explanation:

Given:

Area of a square field = 2.25 hectares

1 hectare = 10000 m²

∴2.25 hectares =
`2.25*10000 = 22500` m²

Now, let each side length of the square field be
`a` meters.

∴ Area =
`a^(2)`

⇒
`22500 = a^(2)`

⇒
`a=√(22500)=150` m

Now, perimeter of a square is given as,
`P = 4a`.

Here,
`a=150` m.

∴
`P=4*150=600` m

Hence, the perimeter of the square field is 600 meters.
