Given:

A typist uses a sheet measuring 20 cm 30 cm length wise.

With margin of 2 cm is left on each side and a 3 cm margin on top and bottom.

To do: Find the percent of page used for typing

Solution:

Length of sheet = 20 cm

Breadth of sheet = 30 cm

Area of sheet =  length × breadth = 600

A margin of 2 cm is kept on left side and right side

So, length of area of typing = 20−(2+2)=16 cm

A 3 cm margin on top and bottom

So, width of area of typing = 30−(3+3)=24 cm

So, area of typing = 16×24=384

So, The percent of the page is used for typing=  384/600×100

Hence 64% of the page is used for typing.
