This Grade 4 math worksheet introduces the square area shortcut, side times side. Students fix sentences about squares with sides like 6 and 9, fill in blanks for areas of 36 and 64 square units, and explain in short answers why a square with side 7 has area 49. Learners practice using square units correctly and compare area to perimeter so they understand which formula fits each Grade 4 question quickly.

Area and Perimeter (Advanced)
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
A square has a side of 6 units, so its area is 6 plus 6, which equals 12 square units.
Rewrite: A square has a side of 6 units, so its area is 6 times 6, which equals 36 square units.
2. Fix the sentence:
The area of a square with side 9 inches are 81 square inches because 9 times 9.
Rewrite: The area of a square with side 9 inches is 81 square inches because 9 times 9 equals 81.
3. Fix the sentence:
Each side of the tile measure 5 cm, so the total area is 25 square centimeters.
Rewrite: Each side of the tile measures 5 cm, so the total area is 25 square centimeters.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. A square with a side of 6 units has an area of 36 square units.
2. The shortcut for the area of a square is side times side.
3. A square tile has a side of 8 cm, so its area is 64 square centimeters.
4. Area is always measured in square units, not in regular length units.
Part C: Short Answer
Answer each question in one or two complete sentences.
1. Explain why the area of a square with side 7 units is 49 square units.
A square has four equal sides, so I use side times side. Multiplying 7 by 7 gives 49, so the area is 49 square units. This shortcut works only because every side of a square is the same length.
2. How is finding the area of a square different from finding the perimeter of a square?
For area, I multiply side by side to cover the surface in square units. For perimeter, I add all four sides or multiply one side by 4 to find the distance around. Area uses multiplication for square units, while perimeter uses addition for length units.
