Question

Number of stamps 3cm×2cm can be fixed on a sheet of paper of 12cm by 8cm is

Answer 1

Answer:

16

Step-by-step explanation:

Let the area of a stamp be b and the area of the sheet of paper be a.

The number of stamps that can be fixed in the sheet should be the area of the sheet divided by the area of a stamp

$b = 3 \times 2 \: {cm}^{2} \\ a = 12 \times 8 \: {cm}^{2} \\ \frac{a}{b} = \frac{12 \times 8}{3 \times 2} \\ \frac{a}{b} = 2 \times 8 \\ \frac{a}{b} = 16$

16 stamps of 2cm by 3cm can be fit in a sheet of 12cm by 8cm

Answer 2

Answer:

Area of stamps = length × breadth

so that , area of paper = length × breath

again,

Number of Stamps =

$= \frac{area \: of \: paper}{area \: ofstamps}$

$= \frac{12 \times 8}{3 \times 2}$

$= 4 \times 4$

= 16 stamps
