Question

A game requires its players to run around a square playground. Each side of the playground is 20 m long. One player took 5 rounds around the playground. How many metres did he run altogether?

Answer 1

Perimeter of a square

= 4 x length of one side 

= 4 x 20 

= 80 m

In one round 80 m. 

So in 5 round 

= 80 x 5 

= 400 

= 400 m

∴ He runs altogether = 400 m
