(i) On measuring, l = 1.8 cm and b = 1.3 cm and
Perimeter = 2 (l + b)
= 2 (1.8 + 1.3) = 2 (3.1)
= 6.2 cm
(ii) On measuring l = 1.5 cm and b = 0.8 cm and
Perimeter = 2 (l + b)
= 2 (1.5 + 0.8) = 2 (2.3)
= 4.6 cm
(iii) On measuring l = 2.1 cm and b= 1.6 cm and
Perimeter = 2 (l + b)
= 2 (2.1 + 1.6) = 2 (3.7)
= 7.4 cm
(iv) On measuring l = 1.8 cm and b= 1.2 cm and
Perimeter = 2 (l + b)
= 2 (1.8 + 1.2) = 2 (3)
= 6 cm
Thus, Perimeter of (iii) figure is greatest.
