Question

If the perimeter of a wall of a room which in a square shape is 140cm, then find the length of the room. ​

Answer 1

Answer:

The length of the square shape room is 35 cm.

Step-by-step explanation:

Let us consider the length of the square shape room be $x.$

The formula to find the perimeter of a square shaped room is given  by :-

Perimeter of a square =$4 \cdot a$

       where,

         a is the side of the square .

      The perimeter of a wall of a room which in a square shape is 140cm .

Mathematically,

                   $4a=140 \hspace {1mm} cm\\ \\ a=\frac{140}{4}\hspace {1mm} cm\\ \\ a=35 \hspace {1mm} cm$

The length of the square shape room will be 35 cm.
