  1. Area of a square is 1/2 hectare. The diagonal of the square is?
    1. 250 meter
    2. 100 meter
    3. 50√ 2 meter
    4. 50 meter
Correct Option: B

Area = 1/2 hectare = 10000 / 2 m2
= 5000 m2

Again Area = 1/2 x (Diagonal)2

So 1/2 x (Diagonal)2 = 5000m2
⇒ Diagonal2= 10000
∴ Diagonal = 100
