Answer:
- 3 mm
⠀
Step-by-step explanation:
⠀
We know,
[tex]{\longrightarrow \qquad \boldsymbol{\pmb{Perimeter_{(square)} \it=4a }}}[/tex]
⠀
Where,
- a is the side length of the square. Here, a = [tex] \sf \: \dfrac{3}{4} [/tex] mm
⠀
Now, Substituting the values in the formula :
⠀
[tex]{\longrightarrow \qquad {\rm{Perimeter_{(square)} = \it4 \times \it \dfrac{3}{4} }}}[/tex]
⠀
[tex]{\longrightarrow \qquad {\rm{Perimeter_{(square)} = \it \cancel4 \times \it \dfrac{3}{ \cancel4} }}}[/tex]
⠀
[tex]{\longrightarrow \qquad {\boldsymbol {\pmb{Perimeter_{(square)} = 3 }}}}[/tex]
⠀
Therefore,
- The perimeter of the square is 3 mm
