Question

the area of a square field is a 8 hectares. how long will you take to cross it diagonally with speed of 4 km per hour ​

Answer 1

area = 8 hectares = 8000 m^2

let a be side

a^2 = 8000

a= 40√5

Diagonal = a√2 = 40√5 × √2 = 40√10

speed = 4 km per hour = 4000 m per hour

time it will take to cross

= 40√10/4000

= 1/10√10 hour

= 60/10√10 min = 6/3.16 = 1.89 min

Answer 2

Answer:

hope this calculation helps you
