Since rectangles have two sets of equal sides, and one side is of length 
, there must be another side of length 
. Since we know the total perimeter of the rectangle, we can get the length of the two remaining sides by subtracting the two known side lengths from the total perimeter. 
, and since the rectangle must have another set of equal sides, we must split 
into two equal parts. Therefore, the last two sides must be

The perimeter is the measurements of all four sides of a square or rectangle. We can use the following formula to solve the problem:
We already know that one side is 15 ft and that the total perimeter is 76 ft, so we can plug those numbers into the formula.
We can subtract 30 from both sides of the equation.
Now we are left with:
We can divide both sides by 2 to find the width of the room.
Therefore, the lengths of the other two sides of the room are 23 ft.
To check to see if our answer is correct we can add the four sides of the room:
This equals 76! (The perimeter of the room in the problem.)
Madison should buy a rug that is 15 ft. by 23 ft.
