Question:
Kanika had a piece of cloth 1 m long and 60 cm broad. She cut it into square shaped handkerchiefs, each measuring 20cm and put a lace on boundary. How much lace is needed for the handkerchiefs
Answer:
Given, Length of cloth = 1 m = 100 cm
and breadth of the cloth = 60 cm
Now, area of the cloth = 100 * 60 = 6000 cm2
Again given, the cloth is cut it into square-shaped handkerchiefs, each measuring = 20 cm
Now, area of the square-shaped handkerchiefs = 20 * 20 = 400 cm2
Number of laces needed = 6000/400
= 60/4 {6000 and 400 are divided by 100}
= 15
