Answer:
360cm²
Step-by-step explanation:
area of full sheet = 20*30cm = 600 cm²
area of margin left in two sides
= 2(2cm X 30cm)= 120cm²
area of margin left in top and bottom
=2(3*20)cm= 120 cm²
area of the page used in typing
= area of full page - (area of margin in two sides + area of margin in top and bottom)
=600-(120+120) cm²
= 600-240 cm²
= 360 cm²
