Question

Answer

Suggested answer:

One group of patterns consists of 3 heart-shaped and 1 diamond-shaped (total 4).

(271 – 3)/4 = 67 group

67 group x 3 + 3 = 204

a) There are 204 heart-shaped cut out.

Length of one group of pattern, ie from 1st heart-shaped to the string right before theĀ 1st heart-shaped of the nest group will be,

5cm + 5 cm + 0.12cm + 0.12 cm = 10.24cm

Total length will be,

10.24cm x 67 + 5cm + 5cm = 696.08cm

b) Length of the string is 696.08 cm.
