Answer 2

Answer:

Length of chartpaper =80

breadth=40

Area of chartpaper without margin = 40×80=3200cm.sq.

lenght of chart paper with margin = 40+6+6=52 cm.

breadth of chartpaper with margin = 80+6+6=92 cm.

Area of chartpaper with margin = l×b= 52×92=4784 sq. cm.

::AREA OF CHARTPAPER WITH MARGIN-AREA OF CHARTPAPER WITHOUT MARGIN = AREA OF MARGIN

4784-3200= 1584 sq. cm

So area of margin = 1584 cm .sq. ANSWER
