Question

how many stamps measuring 5cm*3cm can be fit on a sheet paper of size 20cm*15cm ?

Answer 1

area of rectangle=l*b=5*3=15cm
area of rectangle=l*b=20*15=300cm
number of stamps= 300/15
=20.
hope it's correct.

Answer 2

20 stamps can fit in the sheet paper.

• Size of the stamp is 5 cm × 3cm.
• Now size of the sheet is 20 cm × 15 cm.
• We have to find the number of  stamps that can fit in the sheet paper.
• Area of the stamp = length × breadth = 5 × 3 =15 cm².
• Area of sheet paper = Length × breadth = 20 × 15 = 300 cm².
• Now, number of stamps that can be made from the sheet paper =

$\frac{Area \ of \ sheet \ paper}{Area \ of \ Stamp}$

= $\frac{300}{15}$ = 20.
