Question

Rohit wishes to tile the floor of his study room and drawing room with tiles of area 4 sq metres. The measurement of both the rooms are as follows :
Study room is 10 m long and 9 m wide
Drawing room is 11 m long and 10 m wide.
Find the following :
a) Total floor area of both the rooms.
b) Number of tiles required to tile the total floor area of the two rooms.

Answer 1

Answer:

Step-by-step explanation :

a. total area of study room = length×breadth

                                              = l×b

                                             = 10×9

                                            = 90m²

total area of dining room= length×breadth

                                              = l×b

                                           = 11×10

                                          =110m²

so total are of both room = 90+110

                                           =200m²

b. Number of tiles required to tile the total floor area of the two rooms

                                             = 200÷4

                                            = 50 tiles

                                             

 

Answer 2

Answer:

1. Total area = 200sq m
2. no of tiles = 50

Explaination:-

Given:

1. Area of the tile is 4 sq. m.
2. length of the study room is 10m.
3. breadth of study room is 9m
4. length of drawing room 11m
5. breadth of drawing room is 10m

Solution:

1. Area of study room =

$length \times breadth$

= 10 into 9

=90 sq m

2. Area of drawing room=

$length \times breadth$

= 11 into 10

=110 sq m

3. Total area = Area of study room + Area of drawing room

= 90 +110

=200 sq m

therefore

no of tiles required = total area/ area of a tile

= 200/4

=50 tiles
