Mathematics

Review: Area of Triangles and Parallelograms is a free printable Grade 5 mathematics worksheet with 13 multiple-choice questions and a complete answer key. Students calculate the area of triangles and parallelograms, identify the correct area formula for each shape, and determine a missing height when the base and area information is provided. The review also checks whether students understand that a triangle’s base and height are perpendicular and that opposite sides of a parallelogram are parallel. The varied questions help teachers see whether students can select the appropriate formula, apply it accurately, use square units, and distinguish the geometric relationships that support area calculations. It is suitable for independent practice, review, or a quick assessment of these measurement and geometry skills.

FAQs

What does this worksheet cover?

This Grade 5 worksheet uses 13 multiple-choice questions to review calculating the area of triangles and parallelograms. Students select the correct formula, solve area problems, find missing heights, use square units, and identify that triangle and parallelogram base-height pairs are perpendicular while opposite parallelogram sides are parallel.

How can I use this worksheet to teach triangle and parallelogram area?

Introduce the two formulas before students begin: base × height for a parallelogram and (base × height) ÷ 2 for a triangle. As students work through the multiple-choice items, ask them to explain why the shape determines the formula and to identify the perpendicular base-height pair before calculating or solving for a missing height.

What mistakes should I watch for when students complete this worksheet?

Watch for students using base × height for a triangle without dividing by 2, or dividing by 2 when finding the area of a parallelogram. Students may also confuse perpendicular base and height with parallel sides, choose cubic instead of square units, or select a distractor based on an arithmetic error when solving for a missing height.

How do I assign and grade this worksheet?

This area of triangles and parallelograms worksheet is available as a printable PDF and as a digital quiz on Wayground, and it includes a complete answer key. For printable submissions, scan student work with the Wayground for Teachers app to grade it efficiently. The printable format also supports schools that want to reduce screen time.

How can I differentiate this worksheet for my students?

Use the worksheet’s Advanced Settings to adjust font spacing or choose a larger font size so the multiple-choice area questions and answer options are easier to read. You can also enable a dyslexia-friendly font or translate the worksheet into another language when those options better support students working with the geometry vocabulary and formulas.
