Question

A squared field is 20 m long. If you are running around it, how many
metres do you travel in one round?

Answer 1

Step-by-step explanation:

Side of square is 20m

The distance travelling in one round will be perimeter of square.

4x20=80

Answer 2

Step-by-step explanation:

If you are running around it, it means your running in the perimeter of the square.

Area = S*S

20*20

400

Perimeter = 4*√A

So,

4*√400

4*20 = 80 m

So we travel 80 metres in 1 round around the square field.
