Question

How many square shaped handkerchiefs side 36 cm can be prepared from a cloth of length 1.8 cm and breath 72 cm ?

Answer 1

It should be 1.8 m
Anyway
No of handkerchiefs = area of cloth / area of 1 handkerchief
1.8 m can also be written as 180 cm
180 * 72 / 36 * 36
It can also be written as 180/36 * 72/36
5*2= 10

Answer 2

Ans.

The area of a handkerchief is
= 36 × 36 cm^2
= 1296 cm^2

1.8 m = 1.8 × 100 cm = 180 cm

So, area of the cloth is
= 180 × 72 cm^2
= 12960 cm^2

Hence the number of handkerchiefs be made
= 12960/1296
= 10
