Question

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

Answer 1

Answer:

Perimeter of the square field is 600 meters.

Step-by-step explanation:

Given:

Area of a square field = 2.25 hectares

1 hectare = 10000 m²

∴2.25 hectares =$2.25\times10000 = 22500$ m²

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

∴ Area = $a^{2}$

⇒ $22500 = a^{2}$

⇒ $a=\sqrt{22500}=150$ m

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

Here, $a=150$ m.

∴ $P=4\times150=600$ m

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