PLEASE HELP ME URGENT Find the perimeter of a quadrilateral with vertices at R (-2, 1), S (-5, 5), T (2, 5), U (5, 1). Round your answer to the nearest hundredth when necessary. (5 points) 22 units 24 units 28 units 36 units
Plot the points, it will be easier to see
(-2,1) to (5,1) for example is 7 units for that one side
this is what i got when I plotted it.
ok, so the top and bottom are horizontal, you can add those up by counting the distances. For the slanted sides, you need to use the pythagorean theorem, with the slant as the hypotenuse of a triangle.
|dw:1421893155527:dw|
so 5 would be the other length?
yep, 3-4-5 triangle the other slant side will be the same
and the final answer would then be 24..correct?
correct
Thank you so so much!!
alyssamaarie, it looks like you used geogebra. If so, then you can use that program to help you compute distances and segment lengths to get the perimeter.
the answer is 24!
