Question

2 Select the correct answer. 3 The length of a rectangle is 2 units greater than its width. If the width is w, which expression gives the perimeter of the rectangle in terms of its width? OA. 4W+3 OB. W-3 5w OD. 6W+ 4

Answer 1

It is important to know that the perimeter of a rectangle is defined by the following formula.

$P=2(w+l)$

According to the problem, the length is 2 units greater than its width.

$l=w+2$

Let's replace the length with its equivalent expression.

$\begin{gathered} P=2(w+w+2) \\ P=2(2w+2) \\ P=4w+4 \end{gathered}$
