the length of a rectangle is represented by (6x − 2), and the width is represented by (x − 1). which expression best represents the area of the rectangle

The room is not in the shape of a square

Step-by-step explanation:

The formula for the diagonal of a square is given as

= √ ( L² + L²)

Where L = length of the side of a square

From the question, we are given the Length of the one side of the wall= 19 inches

Length of the diagonal = 20.62 inches

To confirm if the shape is truly a square we use the formula for the diagonal of the square

= √( L² + L²)

= √(19² + 19²)

= √722

= 26.870057685 inches

Approximately = 26.87 inches

When we compare the calculated diagonal, to the diagonal of the wall given in the question, they are not the same.

26.87 inches ≠ 20.62 inches

Therefore, the room is not in the shape of a square.
