Question

8. How many rectangular tiles of dimension 15 cm x 10 cm will be required to cover the floor of a
square ground whose side is 12 metres?​

Answer 1

Answer:

9600 tiles

Step-by-step explanation:

Given:

area of 1 rectanguglar tile =  l*b

                                          = 15*10

                                          = 150 sq. cm

area of square ground = 12*12 sq. m

[since 1m=100cm]

                                       = 1200*1200 sq. cm  

                                       = 1440000sq. m

number of tiles requred = area of ground/area of rectangular

                                        = 1440000/150

                                        = 9600 tiles
