Question

the area of a square field is 50625msq. a man cycles along it's boundary at 18km/hr.In how much time he return at the starting point? ​

Answer 1

Answer:

90

Step-by-step explanation:

area of square fiels is 50625

so, a²=50625

a=√50625

a= 225 m

therefore , perimeter of square = 4a

= 4(225)

= 450 m

given, speed of man is 18 km/ hr

but distance is in metres

so , speed of man = 18 x 5/18

= 5 m/ sec

we know that , time = distance/ speed

= 450/5

= 90sec

(or)

1 min 30 sec
