Question

find the area of a square field is 720801 square A man cyclist along its boundary at 18 km per hour in how much time will he returned to the starting point​

Answer 1

Answer:

Step-by-step explanation:

Area of the field=

We know the formula

(for a square).

⇒720801=side²

⇒side=√720801

⇒side=+849 m or - 849 m.

Neglecting -ve value side=849 m.

⇒Perimeter=4*Side(For a square)

⇒P=849*4 m (Which is also the total distance)

⇒Speed= 18 km/h

⇒18 km/h=18* m/s=5 m/s.

⇒Time=distance/speed

⇒849*4/5

=169*4 seconds

 =679 seconds.

Ans:The required time is 679 seconds.
