Question

the area of a square field is 60025 metre. a man cycles along its boundary at 18 km/h. in how much time will he return to starting point?

Answer 1

Answer:

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.

Answer 2

Answer:

He will return to starting point in 196 seconds.

Step-by-step explanation:

Area of square field = 60025  sq.m.

Area of square =

So,  

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

So, Perimeter of square field =

Perimeter of square field =

Perimeter of square field =

So, Total distance = 980 m

Speed = 18 km/h =

Hence he will return to starting point in 196 seconds.
