there are 2 ways of doing this one is you find the distance of ab, bc, cd and da and then add the answers together. there is another way but i dont remember it properly so i am just gonna do it this way

distance between 2 point = $\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}$

$d = \sqrt {(4 - 1)^2 + (4 - 1)^2}$

$d = \sqrt {(3)^2 + (3)^2}$

$d = \sqrt {9 + 9}$

$d = \sqrt 18$

AB = 4.24

now repeat the same with all

BC= 4.24

CD= 4.24

DA= 4.24

so its a square with all the same sides so perimeter is 4 x 4.24

perimeter is 16.96

hope this helps

mark me as brainliest please

you bought 5 chocolate bars and 8 blow pops for $23.25 your sister bought 2 chocolate bars and 13 blow pops for 21.55 how much d

kirza4 [7]

Answer:

$2.65

Step-by-step explanation:

Let chocolate bar = c and blow pops = b

<u>As per given we have equations below:</u>

5c + 8b = 23.25
2c + 13b = 21.55

<u>13 times the first equation minus 8 times the second to eliminate b and find c:</u>

13(5c + 8b) - 8(2c + 13b) = 13(23.25) - 8(21.55)
65c - 16c = 129.85
49c = 129.85
c = 129.85/49
c = 2.65

Each chocolate bar costs $2.65
