Question

A side of one polygon is 18 meters and the corresponding side of a second similar polygon is 24 meters. If the perimeter of the first polygon is 60 meters and its area is 1000
square meters, find the perimter and area of the similar polygon.

Answer 1

Primeter is proportional to (side)
Area to (side)^2

Answer 2

I don't get what you mean.

Answer 3

primeter = (24/18)*60
area = (24/18)^2 * 1000

Answer 4

does ^2 mean square root?

Answer 5

NO square

Answer 6

I mean squared!

Answer 7

not square root, sorry.

Answer 8

18 --- 60
24 --- x
x=(24*60)/18 = (24*10)/3 = 8*10 =80 will be the perimeter of secondly polygon

area =

18 ---- 1000
24 ---- x
x=(24*1000)/18 = (4*1000)/3 = 4000/3 =1333,3

Answer 9

where did you get the 3 in the area?

Answer 10

simplify 24 and 18 by 6

Answer 11

so you have to find the greatest common factor?

Answer 12

yes

Answer 13

So the area for that other polygon is 1333.3?

Answer 14

after simplify end get the result of area

Answer 15

and

Answer 16

yes

Answer 17

hope that is understandably

Answer 18

So what is the formula you use? The other person's formula for finding the perimiter is similar to yours, but for the area, you guys have different formulas.

Answer 19

I just don't understand how you use 3, if the gcf is 6. don't you divide by 6 instead of 3?

Answer 20

indifferent
so if you see that for side 18 have got area equal 1000 so than for side 24 will be x

Answer 21

so 24 and 18 you can divide exactly by 6
24/6 =4
18/6 =3

Answer 22

ok ?

Answer 23

Ohhhh yes! Got it.

Answer 24

Thank you for your help jhonnyy!

Answer 25

my pleasure

good luck
