Question

the area of square field is 63504msquare. How much time will a man take to completeround along with boundary,if he cycles at a constant speed of 26.88 km/h

Answer 1

Answer:

2.04 minutes.

Step-by-step explanation:

let side of a square = a

then area of a square = a^2 = 63504 m^2.

$then \: a = \sqrt{63504} = 252.$

distance (d) = boundary of field = perimeter of square = 4×a = 4×252 = 908 m

as we know that,

speed = distance/time

time = distance/speed

= (908 m)/(26.88 km/h)

= (0.908 km)/(26.88 km/h) as 1000m = 1km

= 0.034 (approximatel) h

= 2.04 minutes
