If we take 4 rounds around a field that is 160m long and 90m wide, what is the distance we walk in kilometres ?

It will be = 2(160+90) * 4 m= 2000 m = 2 km

4.5

Distance walked = 2 km

Step-by-step explanation:

Dimensions \: of \: a \: rectangular \: field :

Length (l)= 160\:m \\Breadth (b)= 90\:m

i) Distance walked 1 round around the field = Perimeter of the rectangle

=> P = 2(160m+90m)

=> P = 2 × 250m

=> P = 500 m

ii) Distance walked 4 rounds around the field = 4P

= 4×500m

= 2000 m

= 2000 × (1/1000) km

/* 1m = (1/1000) km */

= 2 km

Therefore,

Distance walked = 2 km
