Answer 1

The length and breadth of the room is given

Length = 8 m

Breadth = 8m

We have to find the cost of covering the floor with tiles

• First, we will find the area of the room

       The formula to be  used will be

      Area = length × breadth

               = 8  × 8

               = 64 m²

• Now, the cost of covering 1 m² is ₹100

      Therefore, the cost of covering 64 m²  = 64 × 100

                                                                      = 6400

The cost of covering the floor with tiles  will be ₹6400

Answer 2

According to the question it is given that,

Length = $8m$

Breadth = $8m$

As we have to find the cost of the covering floor,

The formula we used for area,

Area = length × breadth

$=>8$ × $8$

$=>64m^2$

Here, the cost of covering the floor with tiles at the rate of ₹$100$ per metre square.

Therefore,

$=>64*100=6400$

Hence, the cost of covering the floor is $Rs. 6400$
