You can put this solution on YOUR website!
The margin on both edges takes away 2(2cm) = 4 cm from length and breadth,
so the length and breadth of the part you write in is
15cm - 4cm = 11cm and
12cm - 4cm = 8cm .
Then, the area of the portion on which you wrote is
%2811cm%29%288cm%29=88cm%5E2
Since the total area of the page is
%2815cm%29%2812cm%29=180cm%5E2 , the area of portion on which you have not written is
180cm%5E2-88cm%5E2=92cm%5E2 .

Then area of the portion on which you wrote is
highlight%2888%29 square centimeters, and
the area of portion on which you have not written is
highlight%2892%29 square centimeters.
