Area of a Rectangle with Fractional Side Lengths is a free printable mathematics worksheet for students in Grades 4–5. It provides 10 multiple-choice questions that ask students to find the area of rectangles when one side length is a mixed number and the other is a whole number. Problems use fractional parts such as 1/3, 1/4, 1/5, 1/8, and 1/10, giving students practice multiplying mixed-number dimensions to determine square-unit area. Use this worksheet for guided practice, independent work, review, or a quick formative check of students’ ability to apply the rectangle area formula with fractional measurements. The multiple-choice format lets teachers quickly identify errors such as using addition instead of multiplication or overlooking the fractional part of a dimension. The worksheet includes a complete answer key for efficient checking and feedback.

This Grade 4–5 worksheet focuses on finding the area of a rectangle when one dimension is a mixed number and the other is a whole number. Its 10 multiple-choice items require students to multiply the two side lengths and select the matching area, including results such as 18 2/3, 6 3/4, and 20 5/6.
First review the formula area = length × width, then model one item by decomposing a mixed number, such as 2 1/3 × 8, into 2 × 8 plus 1/3 × 8. Have students solve a few of the 10 multiple-choice problems while explaining how they handled the fractional part, and use the answer choices to discuss why adding the dimensions or using only the whole-number part gives an incorrect result.
Students may multiply only the whole-number part of a dimension, add the two side lengths instead of multiplying them, or miscalculate the fractional product. Watch especially for errors when the answer is written as a mixed number, such as 25 2/4 or 15 4/10, because students may select a distractor that reflects an incorrect treatment of the fraction.
On Wayground, assign it as a printable PDF or use it as a digital quiz containing the 10 multiple-choice questions about rectangle area with fractional side lengths. The worksheet 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 supports classrooms that want to reduce screen time.
Use the worksheet’s Advanced Settings to adjust font spacing or font size so the 10 area problems and their answer choices are easier to read. You can also enable a dyslexia-friendly font or translate the worksheet into another language when that supports access to the mixed-number multiplication tasks.
