Question

If a square has the perimeter of 15.2 centimeters, what are 2 equations that can determine the perimeter of the square?

Answer 1

1)
`P=4s`

2)
`P=4√(A)`

see the explanation

Explanation:

we know that

The perimeter of the square is equal to

`P=4s`

where

s is the length side of the square

we have

`P=15,2\ cm`

substitute

`15.2=4s`

solve for s

`s=15.2/4=3.8\ cm`

The area of a square is equal to

`A=s^2`

substitute

`A=3.8^2=14.44\ cm^2`

we have that

`s=√(A)`

therefore

2 equations that can determine the perimeter of the square are

1)
`P=4s` ---->
`P=4(3.8)=15.2\ cm`

2)
`P=4√(A)` ---->
`P=4√(14.44)=15.2\ cm`
