Math(geometry) help please??

Question

PERIMETER The coordinates of the vertices of a quadrilateral are R(-1, 3), S(3, 3), T(5, -1), and U(-2, -1). Find the perimeter of the quadrilateral. Round to the nearest tenth.

Please and thank you!! :)

Answer 1

No way am I doing your homework....

Answer 2

Not enough information... what does each square equal?

Answer 3

answer mine

and umm il get back to you it will take while

Answer 4

find the distance between R and S, S and T, T and U, and U and R. then add the 4 distances together, and you have the perimeter.

Answer 5

Find the length of each of the 4 sides and add them together.

Use Pythagoras. Or you could just measure it.

Answer 6

just find distance between each point and add them

RS=4

TU= 7

ST=sqrt(20)

RU=sqrt(17)

now add them, to the nearest tenth, i'll leave tht up to u

ur quadrilateral is not drawn correctly by the way

Answer 7

first plot the points on the x and y graph.

then get distance between points: r-s, s-t, t-u and u-r

R-S: 4

S-T: use the pythagorean formula = 5

T-U: 7

U-R: again use the pythagorean formula = 4.12

add all = 20.12 round to 20

ps

i think your graph is wrong. i think the first number corresponds to x and the second number is y. so for R, x=-1 and y=3.
