What is the area and perimeter of a rectangle with x+6 on the bottom?

Oct 1, 2015

Area $= x y + 6 y$
Perimeter $= 2 \left(x + y + 6\right)$
$\textcolor{w h i t e}{\text{XXX}}$ where $y$ is the length of the side

Explanation:

Possibly the length of the side was accidentally omitted or perhaps the shape was intended to be a "square" instead of a "rectangle" (in which case the length of the side would be (x+6)).

With the given data, the most we can do is assign another variable (I used "y") for the length of the side.

"x+6 on the bottom" I have interpreted as meaning that the width is $\left(x + 6\right)$ units.

The area of a rectangle is given by the formula:
color(white)("XXX")"Area" = "width" xx "height"

The perimeter of a rectangle is given by the formula
$\textcolor{w h i t e}{\text{XXX")"Perimeter" = 2 ("width" + "height}}$
