I. A square with an area of 36 sq. cm.
II. An equilateral triangle with a side of 9 cm.
III. A rectangle with 10 cm as length and 40 sq. cm as area.
IV. A circle with radius of 4 cm.
- III > I > II > IV
- IV > I > II > III
- III > II > I > IV
- III > II > IV > I
Answer and explanation
Correct answer: D - III > II > IV > I
Perimeters: I side 6 -> 24 cm; II 3 x 9 = 27 cm; III breadth 4 -> 2(10 + 4) = 28 cm; IV 8π = 25.13 cm. Descending: III > II > IV > I.
