Question

Areaof square field is1/2hector find length of itsdiagonal

Answer 1

Area of square = a² = 1/2

a= √1/2 = 1/√2

Diagonal length = √2*a = √2*1/2 = 1

Answer 2

Let the length of each side of square be 's'.

Now, the area of the square = 1/2 of hectare = 0.5 hectare

1 hectare = 10000 sq m

So, 0.5 hectare = 5000 sq m

Now,

Side × Side = 5000 sq m

Side = √5000

Side = 50√2 m

Length of the diagonal of square = √2s

= 50 × √2 × √2

= 50 × 2 

Length of diagonal of square = 100 m
