Given the formula for the perimeter of a rectangle where l represents the length and w represents the width. What does the 2 represent in this formula?

2(l + w)

A The 2
represents the two dimensions of the rectangle.The 2 represents the two dimensions of the rectangle.
B The 2
represents the two width pairs.The 2 represents the two width pairs.
C The 2
represents the two length pairs.The 2 represents the two length pairs.
D The 2
represents the two sets of length and width pairs.The 2 represents the two sets of length and width pairs.

1 answer

The correct answer is:

D The 2 represents the two sets of length and width pairs.

In the formula for the perimeter of a rectangle, \( P = 2(l + w) \), the "2" indicates that there are two lengths and two widths in a rectangle, hence you calculate the total perimeter by summing the lengths and widths and then multiplying by 2.
