Question

The length of a rectangular room is 7.3 feet longer than the width, x,

of the room. Which expression represents the perimeter of the room?

Answer 1

14.6+4x

Explanation:

permimeter=length(2)+width(2)

7.3+x would be the length

so if you multiplied (7.3+x)2, you would get 14.6+2x if you distributive property.

Then if you multiply the width, x, by 2, you get 2x.

So we would get 14.6+2x+2x when we add them together.

And that would be 14.6+4x if you combine like terms.

And that would be your answer.
