Question

the area of a square field is 2 hectare find the length of its diagonal
​

Answer 1

The area of a square can be found using the formula A = s^2,  

2 hectare = s^2

s^2 = 2 * 10^4 m^2 (1 hectare = 10^4 m^2)

s = √(2 * 10^4)

s = 140 m

The length of the diagonal of a square can be found using the formula d = √(2s^2), where s is the length of a side of the square. So, for a square with side length s = 140 m:

d = √(2 * 140^2)

d = √(2 * 19600)

d = √(39200)

d = 198 m

So, the length of the diagonal of a square field with an area of 2 hectare is approximately 198 m.
