Question

8. A picture is painted on a cardboard 11 cm long and 8 cm wide, leaving a margin of 1.5 cm
along each of its sides. Find the total area of the margin in meter.​

Answer 1

Answer:

LENGTH OF PAINTED CARDBOARD=11CM

BREADTH OF PAINTED CARDBOARD=8CM

SINCE THERE IS A MARGIN OF 1.5CM LONG FROM EACH OF ITS SIDE.

THEREFORE REDUCED LENGTH= 11 -(1.5+1.5) = 11-3= 8CM

AND REDUCED BREADTH=8-(1.5+1.5) = 8-3=5CM

so area ot margin = area of cardboard ( ABCD) - (EFGH)

= ( AB×AD) - ( EF× EH)

= 11×8 - 8×5

=88-40

= 48 square CM
