This Grade 4 worksheet focuses on perimeter as the total distance around a rectangle or square. Students add all sides or apply the 2L + 2W shortcut and label answers in regular units such as feet, meters, inches, and centimeters. Activities include error correction, fill-in-the-blank measurement problems, and short answer reasoning rooted in CCSS 4.MD.3. Students measure all sides and add carefully, sharpening the Grade 4 rectangle-perimeter formula and quick mental math for shorter shapes.

Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
The perimeter of a 5 m by 3 m rectangle is 15 meters.
Rewrite: The perimeter of a 5 m by 3 m rectangle is 16 meters.
2. Fix the sentence:
A square with side 6 ft has perimeter 12 feet.
Rewrite: A square with side 6 ft has perimeter 24 feet.
3. Fix the sentence:
A rectangle 7 in by 2 in has perimeter 14 square inches.
Rewrite: A rectangle 7 in by 2 in has perimeter 18 inches.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. A rectangle with length 8 cm and width 5 cm has perimeter 26 centimeters.
2. A square with side 9 ft has perimeter 36 feet.
3. A rectangle 12 m by 4 m has perimeter 32 meters.
4. A rectangle 10 in long and 7 in wide has perimeter 34 inches.
Part C: Short Answer
Answer each question in one or two complete sentences.
1. Explain in your own words how to find the perimeter of a rectangle in Grade 4.
To find the perimeter, add the lengths of all four sides. For a rectangle, you can use 2L + 2W. For example, a 9 m by 4 m rectangle has perimeter 2(9) + 2(4) = 18 + 8 = 26 meters.
2. Why is perimeter measured in regular units like meters, but area is measured in square meters?
Perimeter is a single length all the way around a shape, so it uses one-dimensional units like meters. Area covers a flat surface using unit squares, so it needs two-dimensional units called square meters.
