XY Coordinate Planes

Objective: I know how to calculate the area of a trapezoid given the xy coordinates of the vertices.

Read the lesson on coordinate planes if you need to lean about ordered pairs and xy coordinate plaies.

Area = square units

We hope that the free math worksheets have been helpful. We encourage parents and teachers to select the topics according to the needs of the child. For more difficult questions, the child may be encouraged to work out the problem on a piece of paper before entering the solution. We hope that the kids will also love the fun stuff and puzzles.
