Question

Q5. A boy is cycling along a square field at the speed of 18 km/hr. In how much time
will he complete 5 rounds if the area of the square field is 9604 may
Speed of boy cycling
18 km/hr - 18X5 = 5wda​

Answer 1

Answer: 216090 hrs
Step-by-step explanation:Area of the square field= 9604 m
Therefore, perimeter of the square field= 9604/4 m
                                                                  =2401 m
Speed of the boy= 18 km/hr.
Distance= 2401 x 5 m
              = 12005 m
We know,
Time= Distance x Speed
Therefore, time taken= 18 x 12005 hr
                                    = 216090 hrs

Answer 2

Answer:

     time = 382 seconds

Step-by-step explanation:

Area of the square = side² = 9604 m²

side² = 9604 m²

side = √9604 m²

side = 98 m

perimeter of square = 4 × 98m = 382m

total distance travelled = 5 × 382 = 1910m

speed = 18 km/hr = 18 × 5 / 18 m/s = 5m/s

time = distance / speed

time = 1910 / 5
