Perimeter of a trapezoid worksheets
A trapezoid's four sides can all be different, so its perimeter is a plain four-number addition with no shortcut. These free printable worksheets drill that one shape, every side labeled.
If they get stuck
Perimeter of a trapezoid
The answer key prints on a separate page.
What's on this sheet
This is the trapezoid cut from the mixed perimeter page. Unlike the parallelogram beside it, it offers no pairing to lean on — the two parallel sides are different lengths and the two slant sides usually are too, so every one of the four numbers has to be read and added.
Why this sheet works
Every edge carries its number, including both slanted sides, and the figure is built from those lengths so it is drawn as exactly the trapezoid described. A child checking the answer against the picture is doing something the drawing supports.
How this one works
One question from a sheet like this one, worked a step at a time — with a sentence saying what just happened and why.
