Answer 2

Kanika needs a lace of 1.2 metre length.

Given data :

Length of the cloth = 1 m = 100 cm

Breadth of the cloth = 60 cm

Handkerchief's one side = 20 cm

So

The area of the cloth = (100×60) = 6000 cm²

Area of one handkerchief = (20×20) = 400 cm²

So, total handkerchief number = 6000/400 = 15

One handkerchief's perimeter = 4×20 = 80 cm

15 handkerchief's perimeter = 80×15 = 1200 cm

So she needs a lace of 1200 cm = 1.2 m length (answer)
