was that helpful??

Answer 2

Answer:

10% of area of the floor is covered by total area of sheet.

Step-by-step explanation:

Given that :

• Size of daily sheet calendar = 10cm x 10cm
• Size of floor of room = 5m x 7.3m

Solution :

• Since, year 2013 is a common year. It has 365 days .
• Area of one sheet of Calendar = 10 x 10 cm²

= 100 cm² = 0.01 m²

• Total area of sheet = 365 x 0.01 m² = 3.65 m²
• Area of floor = 5 x 7.3 m² = 36.5 m²
• Let, x% of area of floor is covered by total area of sheet of Calendar. Then,

$\frac{x}{100} \times 36.5 = 3.65 \\ x = \frac{3.65 \times 100}{36.5} \\ x = 10$

• Hence, 10% of area of floor is covered by sheets of Calendar.
