Question

the area of a square field is 1369 m square how much time will it take to run 7 times around it at the rate of 3 km per hour

Answer 1

Area of square field = 1369 m^2

=> Side^2 = 1369

=> Side of square field = 37 m

Now,

Perimeter of field = 4 ×Side

= 4×37

= 148 m

Distance to be travelled in 1 time = 148 m

=> Distance to be travelled in 7 times = 7 × 148

= 1036 m

= 1.036 km

Speed = 3 km/h

Time = Distance / Speed

= 1.036 / 3 hours

= 1.036 × 60 / 3 minutes

= 1.036 × 20 minutes

= 20.72 minutes

Answer 2

Area of square field = 1369 m^2

=> Side^2 = 1369

=> Side of square field = 37 m

Now,

Perimeter of field = 4 ×Side

= 4×37

= 148 m

Distance to be travelled in 1 time = 148 m

=> Distance to be travelled in 7 times = 7 × 148

= 1036 m

= 1.036 km

Speed = 3 km/h

Time = Distance / Speed

= 1.036 / 3 hours

= 1.036 × 60 / 3 minutes

= 1.036 × 20 minutes

= 20.72 minutes
