Question

if the area of a square field is 9 hectares then what is the length of each of its side.​

Answer 1

Answer:

Given that

Area = 9 hectares  

Rate = Rs. 32 / m

To find

Area = 9 hectares  

Area (metre) = 90,000 squared metres  

Area of a square = $a^{2}$

$90,000m^{2}$= $a^{2}$

$\alpha$= $\sqrt{90,000}$

a = 300 m  

Therefore, the side of the square field is 300.  

Now, we'll find it's perimeter.  

Perimeter = 4a

Perimeter = 4(300)  

Perimeter = 1200m  

Cost of fencing the square field = perimeter x rate  

Cost of fencing the square field = 1200 x 32  

Cost of fencing the square field = Rs. 38,400

Therefore, cost is Rs. 38,400.

Answer 2

AREA OF SQUARE FIELD=9 HECTARES

we know,

1 hectare=10000m²

so,9 hectares=(10000×9)m²

=90000m²

For finding area of a square surface= side × side

So,we can form the equation as,

side×side=90000

=>side²=90000

=>side=√90000

=>side=300

Hence, the length of each side of the field is 300m
