To compare areas:
- Calculate each shape's area using Length x Width (or count squares)
- Compare the numbers
- Larger area = more space inside
Two shapes with the same area can look very different!

Compare Area of Two Shapes
Solved Examples
1
Worked Example
Which has larger area: a 3x5 rectangle or a 4x4 square?
SolutionRectangle: 3x5=15 cm². Square: 4x4=16 cm². 16 > 15, so the square has larger area.
2
Worked Example
Compare shapes: one 2x6 (12 cm²), another 3x5 (15 cm²).
Solution3x5=15 cm² > 2x6=12 cm². The 3x5 shape has larger area.
3
Worked Example
Two shapes both have area 24 cm². Can they look different?
SolutionYes! A 4x6 rectangle and a 3x8 rectangle both have area 24 cm² but look completely different.
Key Points
- Calculate each area, then compare the numbers.
- Larger number = more area.
- Same area does not mean same shape — different dimensions can give same area.
