James wants to tile his floor using tiles in the shape of a trapezoid. To make the pattern a little more interesting he has decided to cut the tiles in

half along the median. The top base of each tile is 15 inches in length and the bottom base is 21 inches. How long of a cut will John need to make so that he cuts the tiles along the median?

The median is the line parallel to the bases and it is at the halfway point http://www.swiftutors.com/admin/photos/median-of-trapezoid.png

jim_thompson5910 · Answer

To find how long the median is, add up the two parallel sides. Then divide by 2. For example, in this link here http://www.immgt.com/new_page_1_files/image029.gif they add up the two sides 10 and 20 to get 30. Then they divided by 2 to get 15

So the answer would be 18 inches?
because I would add 15=21=36 then I would divide that by 2 which is 18?...

you have it correct @marcellesitt

jim_thompson5910 · Answer

btw I think you meant to say 15+21 = 36

Thank you so much!!!

mathstudent55 · Answer

The median of a trapezoid is the segment that connects the midpoints of the non-parallel sides.
The length of the median is the average of the length of the bases.

yes, that's what I meant to say... sorry! but thank you for the help!
