To do: To find its dimensions.
Solution:
As given, the breadth of a rectangle is equal to its length.
Therefore it is a square.
Let $a$ be the side of the given shape.
$\therefore$ Perimeter of the square$=4a=88$ [Given perimeter$=88\ cm$]
$\Rightarrow a=\frac{88}{4}$
$\Rightarrow a=4\ cm$.
Thus, the given shape is a square with $4\ cm\times4\ cm$ dimensions.
