13.6 Area of Rectangles

22 questions

3rd - 3rd Grade

Mathematics

This Grade 3 mathematics worksheet develops students’ understanding of the area of rectangles. Students use the formula A = length × width to calculate area from given side lengths, record answers in square units, determine an unknown length or width when the area is known, and recognize that doubling both side lengths does not simply double the area. The 22 questions include 17 fill-in-the-blank items, 3 multiple-choice questions, and 2 drag-and-drop activities. Application problems place rectangle area in familiar contexts, including a playground, quilt, rug, and room. Students also subtract the area of a rug from a room’s total area to find the uncovered space. This free printable worksheet with an answer key supports guided practice, independent work, or a quick check of Grade 3 area skills, while the varied question formats give teachers multiple ways to assess formula use, unit labeling, and reasoning about dimensions.

FAQs

What does this area of rectangles worksheet cover?

This Grade 3 worksheet practices finding the area of rectangles by multiplying length by width and expressing answers in square units. Its 22 items include fill-in-the-blank calculations, multiple-choice reasoning, and drag-and-drop activities, including problems with an unknown side, uncovered space, and the effect of doubling both dimensions.

How can I use this worksheet to teach students how to find the area of rectangles?

Introduce A = length × width with a rectangle whose dimensions and square-unit label are visible, then model how the side lengths produce the area. Use the direct-calculation items first, discuss why answers need units such as square feet or square meters, and finish with the quilt, rug, and room problems so students apply the formula and subtraction in context.

What mistakes should I watch for on this rectangle area worksheet?

Watch for students adding the length and width instead of multiplying, writing a linear unit instead of a square unit, or reversing the process when finding an unknown side from a given area. In the rug problem, students may report the rug’s area rather than subtract it from the room’s area, and in the scaling question they may assume doubling both side lengths only doubles the area.

How do I assign and grade this area of rectangles worksheet?

You can assign the worksheet as a printable PDF or as a digital quiz on Wayground. It includes a complete answer key, and printable submissions can be graded by scanning student work with the Wayground for Teachers app. The printable format also gives schools an option for reducing screen time.

How can I differentiate this rectangle area worksheet for my students?

Use the worksheet’s Advanced Settings to adjust font spacing or increase the font size so the fill-in-the-blank calculations and multi-step rug problem are easier to read. You can also apply a dyslexia-friendly font or translate the worksheet into another language, helping students access the rectangle-area directions, units, and word problems.
