The perimeter of a rectangle is 6z − 14.
Which of the following could represent the length and width of the rectangle?

A) length = 4z − 5, width = 2z − 9

B) length = 2z + 3, width = z − 10

C) length = 4z + 3, width = 2z − 10

D) length = 3z − 5, width = 3z − 9

Answer 1

Whats the formula for the perimeter of a rectangle?

Answer 2

Almost, that's for area though

Answer 3

There are 4 sides to a rectangle, so it would be 2w + 2l. 2 width sides and 2 length sides

Answer 4

and?

Answer 5

...and?

Anyways, when working each answer choice, they only gave you length and width of one side, so you would need to multiply both the width and length by 2, and then combine like terms
