Step-by-step explanation:
The common difference d of an arithmetic sequence is
d = -
=
-
Substitute in values and solve for k, that is
5k - 1 - 2k = 6k + 2 - (5k - 1)
3k - 1 = 6k + 2 - 5k + 1
3k - 1 = k + 3 ( subtract k from both sides )
2k - 1 = 3 ( add 1 to both sides )
2k = 4 ⇒ k = 2
--------------------------------------------------------
The n th term of an arithmetic sequence is
=
+ (n - 1)d
= 2k = 2 × 2 = 4 and
d = 5k - 1 - 2k = 3k - 1 = (3 × 2) - 1 = 5
Hence
= 4 + (7 × 5) = 4 + 35 = 39
Answer:
The perimeter of the polygon = 18 units
The area of the polygon will be square units
Step-by-step explanation:
<u><em>Computing the Perimeter of the Polygon: </em></u>
Considering the polygon with vertices
- W (11,2)
- X (11,8)
- Y (14,8)
- Z (14,2)
As the polygon is drawn in coordinate plane as shown in figure a.
From the attached figure a, we can observe that
- The length of the side
units
- The length of the side
units
- The length of the side
units
- The length of the side
units
So, the perimeter of the polygon can be calculated by taking the sum of the lengths of all sides i.e.
The perimeter of the polygon =
= 3 + 6 + 6 + 3
= 18 units
<u><em>Computing the Area of the Polygon: </em></u>
Area can be calculated by multiplying the length and width of the polygon.
So, the area will be:
Therefore, the area of the polygon will be square units
