Question

The area of a square field is 60025 m sq. A man cycles along its boundary at 18km/h . In how much time will he return to the starting point?
PLEASE GIVE STEP BY STEP EXPLANATION
(irrelevant ans will be reported , and best will get brainliest)

Answer 1

Answer:

196 seconds

Explanation:

Given :

Area of the square field = > 60025 m²

Speed of cyclist = > 18 km/h

= 18 × (1000/60×60)

= 5 m/s²

To Find :

• How much time cyclist will take when he return to the starting point.

Solution :

We don’t know the side of the square,it’s only given the area of the sq so let’s find the side area of square.

Area of square = Side²

Put there values,

$\to \sf{} 60025= Side^2$

$\to\sf{}\sqrt{60025}=\sqrt{(Side)^2}$

$\to\sf{} Side= 245$

Therefore,Perimeter of the square :-

Perimeter of the square = 4 × side

=> 4 × 245

=> 980

We know Speed = Distance/Time

so,Time = Distance/Speed

Hence,

$\to\sf{} Time =\dfrac{980}{5}$

$\to \sf{} Time =\dfrac{980}{5}$

$\therefore\sf{} Time =196$

Therefore it will take 196 seconds
