Answer»

ong>Answer:

AREA of 4 WALLS= 2h (l+b)

=2×3 (5+4) =54m^2 .

Area of ceiling = (l×b) =20m^2 ,

Area of floor is equal to ceiling area as room is of cuboidal shape , so area is 20m^2.

Area of 4 walls +area of ceiling =(54+20) m^2 =74m^2.

total cost = RATE × area = ( 30×74) =222 rupees

a room is 5m long and 3 m wide . if on all its four walls a 40 cm broad paper is pasted upto the height of 1 m. what will be the length of the paper​

AREA of 4 WALLS= 2h (l+b)

=2×3 (5+4) =54m^2 .

Area of ceiling = (l×b) =20m^2 ,

Area of floor is equal to ceiling area as room is of cuboidal shape , so area is 20m^2.

Area of 4 walls +area of ceiling =(54+20) m^2 =74m^2.

total cost = RATE × area = ( 30×74) =222 rupees
