length of paper sheet = 30 cm
breadth of paper sheet = 20 cm
area of paper sheet = area of rectangle
= length × breadth = 30 × 20
= 600 cm^2
side of the strip cut off from each corner
= 4 cm
area of each strip = area of square
= side × side = 4 × 4 = 16 cm^2
area of all ( 4strips) = 4 × 16 = 64 cm^2
area of the remaining sheet
= total area of sheet - area of 4 strips (cut off)
= 600 - 64 = 536 cm^2
Answer:
-------------
area of remaining sheet = 536 cm^2
area of each strip cut out = 16 cm^2
breadth of paper sheet = 20 cm
area of paper sheet = area of rectangle
= length × breadth = 30 × 20
= 600 cm^2
