Answer:-
Given:
The length of a rectangular piece is twice the side of a square piece.
Let the side of the square be x cm.
So, Length of the rectangle = 2(x) = 2x cm
Also given that,
Width of the rectangle = 3 cm
Area of the rectangle = 108 cm²
We know that,
Area of a rectangle = length * breadth
According to the question,
⟹ (2x)(3) = 108
⟹ 6x = 108
⟹ x = 108/6
⟹ x = 18 cm
∴ Each side of the square is 18 cm.
