Question

A square park has an area of 6561 square meters. If you walk around the park what is the distance that you would have walked?

Answer 1

First we have to find length of 1 side of the square. We can use formula for area of the square. A=a*a ==>
`A=a^2` where a is length of the side.
From this formula we can find

`a= √(A)`
a=
`√(6561) =81 - 1 side`
Now we just have to multiply it by 4, because there are 4 sides.
81*4=324 - its the answer
