find the area in square metre of a piece of cloth 1m 25 cm wide and 2 m long ??

Length of cloth = 2 m

Breadth of cloth = 1 m 25 cm

We have to find area in m².

So, we have to convert breadth 1 m 25 cm in meters.

We know, 1 m = 100 cm

means 1 cm = .01 m

$\Rightarrow 25 \mathrm{cm} = 25 \times .01 \mathrm{m} = .25 \mathrm{m}$

Thus,

Breadth of cloth = 1 m + 0.25 m = 1.25 m

Now, Area of cloth = Length $\times$ Breadth = 2 $\times$ 1.25 = 2.5 m²
