A has an area of 18 square units and Shape B has an area of 20 square units, Shape A has a longer perimeter than Shape B.
Shape A: Dimensions = 1 × 18, Area = 18, Perimeter = 38 units.
Shape B: Dimensions = 4 × 5, Area = 20, Perimeter = 18 units.
Shape A has a longer perimeter than Shape B.
Class 6 NCERT Ganita Prakash Chapter 6 Perimeter and Area
class 6 Mathematics Textbook Chapter 6 question answer
For Shape A:
Dimensions = 1 unit × 18 units
Area = 1 × 18 = 18 square units
Perimeter = 2 × (1 + 18) = 38 units.
For Shape B:
Dimensions = 4 units × 5 units
Area = 4 × 5 = 20 square units
Perimeter = 2 × (4 + 5) = 18 units.
Thus, Shape A with a longer perimeter and Shape B with a smaller perimeter satisfy the given conditions.
