The perimeter of a rectangle is the sum of the lenths of its four sides. Which expression, where / = length and w= width, does n

ANTONII [103]

Answer:

Perimeter of a rectangle = 2(L + W)

Step-by-step explanation:

L = length

W = width

In a rectangle, of the four sides, there are two equal length and 2 equal width

Length = 2 sides

Width = 2 sides

perimeter of a rectangle is the sum of the lenths of its four sides.

Perimeter of a rectangle = L + L + W + W

= 2L + 2W

Factorize

= 2(L + W)

Perimeter of a rectangle = 2(L + W)

This expression shows the relationship
