Triangle area: base 28 cm - practice and answers

Use a perpendicular height measurement to calculate the area of a triangle. This original three-page pack focuses on area of triangles with base 28 centimeters. The first two pages provide twenty-four distinct exercises with blank working space. The third page gives the matching answers, kept separate so it can be removed before practice. One example from this exact pack is "Base 28 cm; height 13 cm"; its answer is "182 square cm". Read the task direction before beginning, and use the key to review reasoning rather than guessing from a pattern. No curriculum certification or learning outcome is promised.

Make it work on your printer.

Multiply the base by the perpendicular height, then divide by two. Use square centimeters. Pages 1 and 2 contain practice A and B; page 3 is the answer key. Print the answer page separately if needed. Equivalent exact answers may be valid even when written differently from the key.

Select the file matching the paper loaded in your printer. Choose portrait orientation and actual size (100%). If your printer clips the edge, use its fit-to-page setting and check the print preview first. Print a single page before making several copies.

For a multipage pack, select the page range you need. Page numbers appear in the lower right of every sheet.
