Question

he will take 4 Round around a field that is 160m long and 90m wide what is the distance we walk in kilometre ​

Answer 1

length of field = 160m =160/1000km=0.16km

breadth of field=90 m =90/1000km =0.09km

perimeter of field = 2(l+b) = 2(0.16+0.09) =2×0.25=0.5km

thus, the distance covered in 1round =0.5km

the distance covered in 4 round = 4×0.5km =2.0km =2km
