Show that 2D shapes with the same area can have different perimeters, and solve related problems
10 tutor-authored questions for this Ontario curriculum expectation, ordered easiest to hardest — every one with a full worked solution. Work through them free, no account needed.
Sample: the first question, solved
A 4cm×4cm square (area=16cm², perimeter=16cm) is compared to a 2cm×8cm rectangle (area=16cm²). Find the rectangle's perimeter and compare.
📘 Worked solution
✓Rectangle perimeter = 2×(2+8)=20cm. Same area, different perimeter (16cm vs. 20cm).
And one from the hard end
Find the perimeter of a 5cm×5cm square (area=25cm²).
