Question

if we take four rounds around a field that is 160 M long and 90 M wide, what is the distance we walk in kilometres?

Answer 1

So given dimensions of the Feild :

Length = 160 m

Breadth = 90 m

Then ,

Perimeter of the Feild

We get hint that the Feild is rectangular in shape.

So perimeter of Feild =

2(Length + Breadth)

The distance Covered in one round =

2(160+90) = 2(250) = 500 m

Then , it is asked about 4 rounds .

Distance covered in 4 rounds = 4 × 500 = 2000 metres.

We know very well that 1000 metres = 1 km

2000 metres = 2 km

Answer 2

Answer:

2 km

Step-by-step explanation:

Perimeter of a rectangle= 2(l+b)units

l=160m

b=90m

2(160+90)=2*250=500m

4 rounds=500m*4=2000m

1km=1000m

2000m=2km

hence distance =2km
