This Grade 4 worksheet introduces finding the area of rectangles and squares using length times width. Students label answers in square units like square inches, square feet, square centimeters, and square meters. Practice covers spot-the-error questions, fill-in-the-blank computations, and short answers that build confidence with the foundational area formula in CCSS 4.MD.3. Students compute small-rectangle areas in square units, building Grade 4 fluency with the multiplication-based area formula and clear unit labeling.

Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
The area of a 5 ft by 3 ft rectangle is 8 square feet.
Rewrite: The area of a 5 ft by 3 ft rectangle is 15 square feet.
2. Fix the sentence:
A square with side 4 cm has an area of 16 cm.
Rewrite: A square with side 4 cm has an area of 16 square cm.
3. Fix the sentence:
A rectangle 7 in by 2 in has area 9 square inches.
Rewrite: A rectangle 7 in by 2 in has area 14 square inches.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. A rectangle with length 6 m and width 4 m has area 24 square meters.
2. A square with side 5 ft has area 25 square feet.
3. A rectangle 9 cm long and 3 cm wide has area 27 square centimeters.
4. A rectangle 8 in by 6 in has area 48 square inches.
Part C: Short Answer
Answer each question in one or two complete sentences.
1. Explain in your own words how to find the area of a rectangle in Grade 4.
To find the area of a rectangle, multiply the length by the width. For example, a rectangle 7 ft long and 4 ft wide has an area of 7 x 4 = 28 square feet. Always label the answer with square units.
2. A garden is 10 m long and 6 m wide. What is the area, and why must the unit be square meters?
The area is 10 x 6 = 60 square meters. Area is measured in square units because it tells how many unit squares cover the garden, so we say square meters, not just meters.
