Given
formula for the perimeter of a rectangle = 2 ( l + w)
where l represents the length and w represents the width.
What does the 2 represent in this formula
To proof
As given in the question
Formula for the perimeter of a rectangle = 2 ( l + w)
where l = length , w = width
Perimeter of a rectangle is equal to the sum lengths of all the four sides.
Rectangle consisted of four sides.
Rectangle opposite sides are of equal length.
The diagram of rectangle given below.
option (D) is correct.
Therefore 2 represents the two sets of length and width pairs.
Hence proved
