Question

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

Answer 1

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

Perimeter =4×s=8 km
side=8÷4=2 km
area =s*s=2×2=4 km sq.
=400 hectares.
