Question

the area of a square field is 50625 meter square .A man ycles along its boundary at 18 km/hr.In how will he return at the starting point

Answer 1

Answer:

Step-by-step explanation:

Hi ,

Let length of the square field = a m

Area of the field = 50625 sq m

a² = 225m × 225 m

a = 225 m

Distance travelled by cycle( P )

= Perimeter of square field

= 4a

= 4 × 225 m

= 900 m

Distance ( d ) = 900 m

Speed ( s ) = 18 km / hr

= 18× (1000/60)m/mi

= 300 m / mi

Let Time = t hr

t = d/s

= 900 / 300

= 3 mi

Therefore ,

Time taken to reach the starting

point ( t ) = 3 mi

I hope this helps you.
