Question

The perimeter of a square filed is 8km. Find its area in hectares.

Answer 1

Answer:

Step-by-step explanation:

Solution :-

Perimeter of the square field = 8 km

Side of the square = Perimeter/4

⇒ 8/4

⇒ Side of the square = 2 km

So, length of each side of the square is 2 km 

Area of square = Side*Side

⇒ 2 km × 2 km

= 4 sq km

As we know that 1 sq km = 100 hectares

So, 4 km = 400 hectares

Hence, the area of the square field is 400 hectares.

Hope this helped!!!!!

Answer 2

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \boxed{ \boxed{\boxed { \huge \mathcal\red{ {solution}}}}}$

Perimeter of square field=8km

$\: ⟹side \: of \: square = \frac{perimeter}{4}$

$\: ⟹ \frac{8}{4}$

$\: ⟹side \: of \: square = 2km$

So the length of each side of square is 2km

Area of square = side ×side

⟹ 2km×2km

⟹ 4sq km

As we know that 1sq km= 100 hecteres

so, 4km =400 hectares

Hence the Area of square field is 400 hectares.
