Question

the area of the square field is 24200sq. m how long will a lady take to cross the field diagonally at the rate of 6.6km/hr?​

Answer 1

Answer:

Area of a square field = 24200 sq m

Let the side of square = a

a^2 = 24200 

=> a = (24200)^(1/2)

Diagonal = (2)^(1/2) * a

= 1.414 * 155

= 220 

Speed of lady = 6.6 km / hour

= 6600 m / hour

= 110 m / min

Time taken by lady to cross the field diagonally = 220/110 = 2 min
