Question

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

Answer 1

Area `=xy+6y`
Perimeter `=2(x+y+6)`
`color(white)("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 `(x+6)` 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
`color(white)("XXX")"Perimeter" = 2 ("width" + "height")`
