Question

A page of a calender is 40 cm long and 25 cm wide. Find the total area of all the calender pages of the month of January.

Answer 1

Calender page is given to be a rectangle.

So, area of each page = L x B = 40 cm x 25 cm = 1000 <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> ${cm}^2$

We know that the month of January has 31 days.
So we have 31 pages for the month of January.

Therefore,
Total area of all the calender pages of the month of January = 31 x 1000 ${cm}^2$ = 31,000 ${cm}^2$
