Answer 2

Concept:

The area is the space occupied by any 2d shape. The area of a rectangle is found by multiplying its length and width.

Given:

Rectangular cloth of length 12m and width 1.2m.

And,

Side of handkerchief = 60 cm

Find:

We are asked to find the number of square handkerchiefs of side 60 cm that can be made from the given rectangular cloth.

Solution:

We have,

Rectangular cloth of length 12m and width 1.2m.

So,

Area of rectangular cloth = Length × Width = 12 × 1.2 = 14.4 m²

NOw,

We have,

Side of sqaure handkerchief = 60 cm = 0.6 m

And,

Area of sqaure handkerchief = side × side = 0.6 × 0.6 = 0.36 m²

Now,

The number of sqaure handkerchiefs = 14.4 / 0.36 = 40

Hence, the number of square handkerchiefs of side 60 cm that can be made from the given rectangular cloth is 40.
