Answer with explanation:

→  Let L be the Length and B be the Breadth of rectangular mat.

     Area of rectangular Mat = Length (L) * Breadth (B)

                                              =L*B square units

→  Let , a be the side of Square.

Area of square =(Side)²

                             =a² square units

→→It is also, given that The area of the square mat is half the area of one of the rectangular mats.

\rightarrow a^2=\frac{LB}{2}\\\\LB=2a^2\\\\ \text{Length of one square mat(L)}=\frac{2a^2}{\text{Breadth(B)}}\\\\\L=\frac{2\times {\text{Area of Square}}}{\text{Breadth of rectangle}}\\\\B=\frac{2\times {\text{Area of Square}}}{\text{Length of rectangle}}

So by definition, area is equal to the length (x) times the width (y). The area of the square mat is = x × y, or xy
If the area of<span> the rectangular mat is twice that of the square mat, the area of the rectangular mat would have to be = 2 </span>× x × y<span>
This can be written as 2x </span>× y, making the length of the rectangular mat twice that of the square mat's length, and the width the same as the square mat's width.<span>
