|dw:1418110056228:dw| Its a square Find distance between points to get the side of the square perimeter of square = 2*side area = side^2

OpenStudy (anonymous):

how do i find the distance @sangya21

OpenStudy (anonymous):

\[d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}\]

OpenStudy (anonymous):

wait the distance is \[3\sqrt{2}\]

OpenStudy (anonymous):

which would be 4.24

OpenStudy (anonymous):

thats your side.

OpenStudy (anonymous):

so the perimeter of square = 4.48

OpenStudy (anonymous):

no sorry 8.48

OpenStudy (anonymous):

and area = 71.9104

OpenStudy (anonymous):

Perimeter = 4* 4.24 = 16.96 Area = side ^2 = (4.24)^2 = 17.977

OpenStudy (anonymous):

thanks
