About this worksheet

What students practice

Students find triangle and special quadrilateral areas using perpendicular heights.
Students decompose polygons into rectangles and triangles to calculate area.
Students apply area calculations to material needs in a community science lab.

How to use

Have students mark useful cuts and record their calculations on scratch paper. Discuss how different decompositions can give the same area.

Curriculum

Common Core standard covered

Community Water Lab: Surface Areas

Split, rearrange, and compare shapes used in a water-quality lab.

Triangle Panels

Use perpendicular heights, not slanted side lengths. Diagrams show shapes; use the measurements stated in each question.

The community lab tests water collected by volunteers. A triangular label for a sample tray has a base of 14 cm and a perpendicular height of 9 cm.

What is the label's area? cm²

A rectangular sheet measures 18 cm by 10 cm. A technician cuts it along a diagonal to make two congruent triangular covers. What is the area of one cover?
