Question

The area of a square is 0.5 hectares. what ia its diagonal

Answer 1

Area =( side) ^2
Therefore , side = square root of 0.5 =1/root 2
Therefore, diagonal = root 2 times side
=1/root 2 * root 2
=1
Therefore, diagonal = 1 hectare

Answer 2

Answer:

Length of diagonal is 1 hectare.

Step-by-step explanation:

Give the area of square which is 0.5 square hectares.  

we have to find the length of diagonal.

$\text{Area of square=}side^2$

⇒ $side^2=0.5$

⇒ $side=\sqrt{0.5}=\frac{1}{\sqrt2}$

As, $\text{length of diagonal=}\sqrt2\times side=\sqrt2\times\frac{1}{\sqrt2}=1 hectare$

Hence, length of diagonal is 1 hectare,
