Question

The area of a square field is 1/2
hectare. Find the length of its diagonal in metres.
2
Hint. 1 hectare =
10000 m²

​

Answer 1

Answer:

Step-by-step explanation:

Area of Square = Side²

=> 5000 m² = Side²

=> Side = √5000 = √(2500 * 2) = 50√2 m.

Length of Diagonal = √2 * Side = √2 * 50√2 = 50 * 2 = 100 m.

Answer 2

Given area of square field =0.25 hectare

1 hectare =10,000m =0.25×10,000

=0.25×100

=2500 sq. m

Let side of square be 'a'

Area of square =a2

a2=2500

⇒a=50m

Diagonal of square =2a=2×50

=502m.
