Answer 1

area = 14*9
          =126 m square
=126*100
=12600 cm
wide =63*x
63x
m=12600/63
200cm
2meter

Answer 2

Answer:

$Required \: carpet = 200\:m$

Step-by-step explanation:

Dimensions of a carpet :

Width(w) = 63 cm = 0.63 m

Let length = l cm

Dimensions of the floor:

Length (L) = 14 m,

Breadth (B) = 9 m,

Now,

area of the carpet = area of the floor

=> l × w = L × M

=> l × 0.63 m = 12m × 9m

$\implies l = \frac{12\times 9}{0.63}\\=200\:m$

Therefore,

$Required \: carpet = 200\:m$
