Answer 2

Answer:

70

Step-by-step explanation:

solution here

length of wall = 14m

breadth of wall =10m

area of wall = 14m*10m

                     =140m²

now,

length of wall paper sheet = 2m

breadth of wall paper sheet = 1m

area of wall paper sheet = 2m*1m

                                          =2m²

then,

number of wall paper sheets needed to cover the wall =140m²/2m²

=70

∴bob would need 70 wall paper sheets to cover the wall
