Question

What is the perimeter of the polygon in the diagram?

Answer 1

__________
2√ (a−b) 2


4(a+b)^ 2


2(a 2 +b 2 )

__________
4√ a 2 +b 2

Answer 2

Note that the length of all the sides of that polygon are the same (they were nice to you)! :-) So all you need to do here is use the distance formula to compute the distance between two points along one of the edges and then multiply your answer by 4. I would recommend finding the distance between the points (a,0) and (0,b).

Does this make sense?

Answer 3

no

Answer 4

Which part doesn't make sense?

Answer 5

i believe its

2(a 2 +b 2 )

Answer 6

or

__________
4√ a 2 +b 2

not sure

Answer 7

can anyone help me?

Answer 8

use the Pythagoras' theorem: the square of a side of the polygon(c) is equal to the sum of the squares of a and b

\[c ^{2} = \alpha ^{2} + \beta ^{2}\]

and since the sides are equal the perimeter would be 4c

Answer 9

it is not c

Answer 10

not c, 4c, but you must find c first. Use the formula above to find c(c is just a variable which i have assigned for the side)

Answer 11

It's D for anyone who needs it
