Question

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

Answer 1

length=2 m
breadth=1 m 25cm ⇒1 m = 100 cm
                                    ∴ 25cm=25/100 ⇒0.25 m
area = l x b
         = 2 x 1.25 m
           = 250m∧2

Answer 2

Answer:

$2.5 m^2$

Step-by-step explanation:

Width of piece = 1 m 25 cm

100 cm = 1 m

1 cm = $\frac{1}{100}m$

25 cm = $\frac{25}{100}m=0.25 m$

So, Width of piece = 1m +0.25 m = 1.25 m

Length of piece = 2 m

Area of piece = $Length \times Width = 1.25 \times 2 = 2.5 m^2$

Hence The area of piece is $2.5 m^2$
