Question

PLEASE HELP ME!!!!!!!!


Which of the following would result from multiplying each side of the polygon by a ratio of 1/2?



The final area is 12km2

The final perimeter is 24km

The final area is 6km2

The final perimeter is 20km

Answer 1

please help me

Answer 2

yes

Answer 3

the final area will reduce

Answer 4

I cannot understan what u want ?

Answer 5

The perimeter will be one-half that of the original polygon.

EX: If the length of the sides of the polygon are w,x,y,z the original perimeter would be
\[P = w+x+y+z\]
And if you decrease the length by half of all the sides you would get
\[P = {1\over 2}w+{1\over2}x+{1\over2}y+{1\over2}z\]
\[P = {1\over2}\left(w+x+y+z\right)\]

As for the area, it should decrease by a factor of 1/4. I'll use the example of a square with sides of length x.

\[A = x^{2}\]
The new area would be
\[A = \left({1\over2}x*{1\over2}x\right)\]
\[A = {1\over4}x^{2}\]

Answer 6

so whats the answer?

Answer 7

Depends on the area and perimeter of the original polygon.......which you haven't given us
