Question
Tick the shapes with the same area. Find the perimeters of these shapes. What do you notice? Discuss.
Answer

(a) Perimeter = 16 cm, Area = 12 cm square
(b) Perimeter = 18 cm; Area = 12 cm square
(c) Perimeter = 14 cm; Area = 12 cm square
(d) Perimeter = 14 cm; Area = 12 cm square
(e) Perimeter = 18 cm; Area = 8 cm square
(f) Perimeter = 26 cm; Area = 12 cm square
Here, area of shapes (a), (b), (c), (d), and (f) is same.
We can see that shapes can have same area but different perimeters.
