Question

the area of a square field is 60025 meter square. a man cycle along its boundry at 18 km/h. In how much time he return to the starting point? ​

Answer 1

Explanation:

He will return to starting point in 196 seconds.

Step-by-step explanation:

Area of square field = 60025 sq.m.

Area of square = Side ^2

So, 60025=Side ^2

\sqrt{60025}=Side

245=Side

Since we are given that he cycles along the boundary of field

So, Perimeter of square field =4 \times Side

Perimeter of square field =4 \times 245

Perimeter of square field =980 m

So, Total distance = 980 m

Speed = 18 km/h =18 \times \frac{5}{18} =5 m/s

Time =\frac{Distance}{Speed}

Time =\frac{980}{5}

Time =196

Hence he will return to starting point in 196 seconds.
