The area of the Logo 1 will be 12.48 square meters and the area of the Logo 2 will be 9.6 square meters.

<h3>What is Geometry?</h3>

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

Now consider the logos for Parkside Printing shown.

Determine the actual area of Logo 1  and Logo 2 in square meters will be

The area of the Logo 1 (A₁) will be

\rm A _1 = 12 \times 8 - 6 \times 3\\\\A_1 = 78 \ cm^2\\\\A_1 = 78 \times 0.16 \ m^2\\\\ A_1 = 12.48 \ m^2

Then the area of the Logo 2 (A₂) will be

\rm A_2 = \dfrac{1}{2} \times 12 \times 10\\\\A_2 = 60 \ cm^2\\\\A_2 = 60 \times 0.16 \ m^2\\\\A_2 = 9.6 \ m^2

The first two terms in an arithmetic progression are 57 and 46. The last term is -207. Find the sum of all the terms in this pro
statuscvo [17]

Answer:

-1875

Step-by-step explanation:

An arithmetic sequence has a common difference as a sequence. Here the common differnece is -11.

So our sequence so far looks like,

(57,46,35,24....). We know the last term of the sequence is -207 and we need to find the nth term of that series so we use arithmetic sequence

a _{1} + (n - 1)d

where a1 is the inital value,

d is the common differnece and n is the nth term.

We need to find the nth term so

57 + (n - 1)( - 11) =  - 207

(n - 1)( - 11) =  - 264

n - 1 = 24

n = 25

So the 25th term of a arithmetic sequence is last term, now we can use the sum of arithmetic sequence

which is

\frac{a  _{1} + a _{n}   }{2} n

\frac{57 + ( - 207)}{2} (25) =

\frac{ -  150}{2} (25)

- 75(25) =  - 1875
