The perimeter of a square must be greater than 122 inches but less than 134 inches. Find the range of possible side lengths that satisfy these conditions. Hint the perimeter of a square is given by p = 4s, where s represents the length of a side).

Respuesta :

Let the perimiter of the square P

Statement 1

The perimeter of the square is greater than 122 inches

This can be expressed in inequality as

[tex]P>122[/tex]

Statement 2

The perimeter of the square is less than 134 inches

This can be expressed in inequality as

[tex]P<134[/tex]

Since P = 4S, hence

[tex]4s>122,4s<134[/tex]

Solving for s gives

[tex]\begin{gathered} 4s>122 \\ \Rightarrow s>\frac{122}{4} \\ \Rightarrow s>30.5 \end{gathered}[/tex]

Aslo

[tex]\begin{gathered} 4s<134 \\ \Rightarrow s<\frac{134}{4} \\ \Rightarrow s<33.5 \end{gathered}[/tex]

Hence

[tex]s>30.5,s<33.5[/tex]

Combining the inequalities gives

[tex]30.5
