Question

a room is 4.8 M long and 3.2 M wide its floor is to construct with square marble tiles 10 centimetre multiply 10 cm find the number of tiles required to cover the floor and the cost of tiles at Rs 18 per dozen

Answer 1

area of room = 4.8 × 3.2 = 15.36 m
1 m^2 = 10000 cm
area of square marble =10 ×10 =100 cm
number of tiles required to cover the floor =
10000÷100 =100 tiles
cost of per dozen tiles = 18
cost of each tiles = 18 ÷ 12 =1.5
cost of 100 tiles =100 × 1.5 =150

Answer 2

Answer:

Step-by-step explanation:

Area of room = 4.8 × 3.2 = 15.36 m

1 m^2 = 10000 cm

area of square marble =10 ×10 =100 cm

number of tiles required to cover the floor =10000÷100 =100 tiles

cost of per dozen tiles = 18

cost of each tiles = 18 ÷ 12 =1.5

cost of 100 tiles = 100 x 1.5 = 150
