Find the area A of polygon CDEFGH with the given vertices. C(0,5), D(2,5), E(2,3), F(3,2), G(-1,2), H(0,3)
enot [183]

Answer:

<em>The area of the polygon CDEFGH is 7</em>

Step-by-step explanation:

<u>Area of a Polygon</u>

The area of a polygon is generally calculated as the sum of the smaller areas that form its full shape, give each partial area has a known shape, like a square, rectangle, triangle, circle, etc.

The six points given in the question are plotted in the image below. They form a polygon whose area can be divided into two smaller shapes:

The area CDHE is a square of length side 2. Area of a square:

A1=L^2

The area HEFG is a trapezoid with bases lengths 4 and 2,  and height 1. Area of a trapezoid:

\displaystyle A2=\frac{b1+b2}{2}h

Calculate both areas:

A1=2^2=4

\displaystyle A2=\frac{2+4}{2}\cdot 1=3

Total Area=4+3=7

The area of the polygon CDEFGH is 7

Which sentence is NOT a geometric progression?
DIA [1.3K]

<u>c) 3, 6, 9 12</u>  is NOT a geometric progression

<h3>Further explanation </h3>

Geometry sequences are series of numbers that have a constant ratio

or can be interpreted:

Each number is obtained by multiplying the previous number by a constant

The sequence can be:

a, ar, ar², ar³, ... etc.

Can be formulated

\large {\boxed {\bold x_n = ar ^ {n-1}}}

where:

a is the first term, and

r is the common ratio

So we have to see the series has the same ratio or not

a. \dfrac{5}{1}=\dfrac{25}{5}=5\to \rm geometric\:progression

b. \dfrac{8}{4}=\dfrac{16}{8}=2\to \rm geometric\:progression

c.\dfrac{6}{3}\neq \dfrac{9}{6}\to \rm not\:geometric\:progression

d. \dfrac{6}{2}=\dfrac{18}{6}=3\to \rm geometric\:progression
