Question

Walls of a room is 10 m long,8 m wide and 5 m high are to be covered with wall paper 50 cm wide. Find the length of wall paper required​

Answer 1

Length of Room in cm. = 1000cm

Width of Room in cm. = 800cm

Height of Room in cm. = 500cm

Area of Wallpaper = CSA of Room (walls)

l x b = 2(l+b)h

l x 50cm. =. 2(1000+800)500

l x 50. =. 2 x 1800 x 500

l x 50. =. 3600 x 500

l x 50. =. 1800000

l = 1800000/50.

Length of wallpaper is 36000cm or 360m.

Thank You :)
