Item 12 a rectangular room is 10 feet longer than it is wide. one-foot-by-one-foot tiles cover the entire floor. let ww represent the width (in feet) of the room. write an expression in simplest form that represents the number of tiles along the outside of the room.

Given:

Rectangular room is 10 feet; and

1 x 1 ft tiles

The expression for this problem would be:

If we know that the width is w, while the length is w + 10, therefore the perimeter is 2w + 2 (w + 10), so you need 4w + 20 - 4, or 4w + 16 tiles. Since you do not want to count the corners, twice.

f(x) = y

f(-3) = -5
