Question

The length of a rectangle is represented by (6x − 2), and the width is represented by (x − 1). Which expression best represents the perimeter of the rectangle?
A) 14x − 6
B) − 8x + 2
C) 6x2 − 8x
D) 6x2 − 8x + 2

Answer 1

Given:

Length = 6x - 2

Width = x - 1

To find:

Perimeter of rectangle

Solution:

Perimeter of rectangle = 2(length + width)

                                      = 2(6x - 2 + x - 1)

                                      = 2(7x - 3)

Perimeter of rectangle = 14x - 6

The expression best represents the perimeter of the rectangle is 14x - 6.
