Answer:
Area = length x width
Area = (3width - 13) x width
Area = 3 width^2 -13width
56 = 3width^2 -13 width
Width = 7
Length = (3 *7) -13 = 8

Step-by-step explanation:
A line segment that goes from one side of the circle to the other side of the circle and doesn't go through the center is called chord of circle.
Since,
The chord of a circle can be defined as the line segment joining any two points on the circumference of the circle.
The diameter is the length of the line through the center that touches two points on the edge of the circle.
So, we can say that every diameter of a circle is always called chord (longest chord) but every chord of the circle is not a diameter because the diameter passes to the circle's center but it not necessay that evey chord will pass through the center of the circle. Some, line segment goes from one side of the circle to the other side and doesn't pass through centre then for this case the line segment is called chord of the circle.
Hence, a line segment that goes from one side of the circle to the other side of the circle and doesn't go through the center is called chord of the circle.

Answer:
The total length of the border is 
Step-by-step explanation:
we know that
The circumference of a circle is equal to
we have
assume
substitute
The length of the carpet's side is 11 feet
Step-by-step explanation:
Step 1 :
The area covered by the carpet = 121 square feet
We need to find the length of side of carpet
Step 2 :
Since it is given that the carpet is square, the length of all sides are the same
The area is obtained by squaring the side. Hence to find the side from the given area we need to take the root of the area.
Side² = 121
Therefore side = √121 = 11 feet
Step 3 :
Answer :
The length of the carpet's side is 11 feet
