Question

the area of a square field is 1369 m^2. how much time will rita take to run 7 times around it at the rate of 3km/h?

Answer 1

Given conditions ⇒

Area of the Square filed = 1369 m²

⇒ a² =  1369

⇒ a = √ 1369

∴ a = 37

Now, Perimeter of the Square field = 4 × 37

= 148 m.

Now, Total distance covered in the 7 round = 148 × 7 = 1036 m. = 1.036 km.

Now, Velocity =  3 km/hr.

∵ Velocity = Displacement/Time

⇒ Time = 1.036/3 hrs.

⇒ Time = 20.72 seconds.

Hope it helps.

HEY DEAR ... ✌️

=) Given ,
Area of a square field = 1369 m^2.

First , To get , Side (a) .

=) a^2 = 1369

=) a = √1369

=) a = 37


Now , easily we can find the perimeter .

So , perimeter of a square field = 4a

=) 4 × 37

=) 148 m

So , To find total distance of 7 rounds .

=) 148 × 7

=) 1036 m

Therefore , Metre to Kilometre

=) 1.036 km

Given , Velocity = 3 km/h

We know , Velocity = Displacement / Time

=) Time = 1.036 / 3 h .

=) Time = 20.72 seconds .
