• A. Square
• B. Rectangle
• C. None of these

Answer 1

The correct option is A

Square

Step 1 : Calculating perimeter of square

Perimeter of square $=4\times$side

$$\begin{gathered} =4\times 5 \\ =20cm \end{gathered}$$

Step 2: Calculating perimeter of rectangle

Perimeter of rectangle $=2$$($length $+$ breadth $)$

$$\begin{gathered} =2\left(5+3\right) \\ =2\left(8\right) \\ =16cm \end{gathered}$$

Hence , perimeter of square is greater .
