we have the coordinates of ABCD
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 = [tex]\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}[/tex]
AB
[tex]d = \sqrt {(4 - 1)^2 + (4 - 1)^2}[/tex]
[tex]d = \sqrt {(3)^2 + (3)^2}[/tex]
[tex]d = \sqrt {9 + 9}[/tex]
[tex]d = \sqrt 18[/tex]
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
