<span>Circles having equal radii are congruent.
Circles having different radii are similar.
The central angle which intercept an arc double of any inscribed angle that intercepts the same arc.
The radius perpendicular to a chord bisects the chord.
The chords equidistant from the center are equal in length.
A tangent to a circle is at right angles to the radius at the point of contact.
Two tangents drawn to a circle from a point out side are equal in length.
The angle subtended at the center of a circle by its circumference is equal to four right angles.
Circumference of two different circles is proportional to their corresponding radii.
Arcs of the same circle are proportional to their corresponding angles.
Radii of the same circle or the equal circles are equal.
Equal chords have equal circumferences.
The diameter of a circle is the longest chord.
Circle which have equal radii are equal.
Equal circles have equal circumference.</span>
Answer:
Regardless of the room's dimensions, the rug's area will be 1/4 the area of the room. Here's a quick way to show this:
Suppose the room is w feet wide and l feet long. The area of the room is w*l. The rug will be (w/2) feet wide and (l/2) feet long. So the area of the rug is (w/2)*(l/2), which equals (w*l)/4, or one-quarter the area of the room.
(Note that the living room being twice as long as it is wide is extraneous information.)
