Question

the side of a square hall is 8m 5dm find the cost of fixing tiles on its floor at the rate of Rs. 300 per sq.m​

Answer 1

Step-by-step explanation:

the Side of the square Hall is 8 meters and 5 decimeters.

so, let convert this measurement into meters .

Hence

Convert 5 decimeters into meters .

As we know that ,

1 decimeter = 1/10 meters

So 5 decimeters = 5/10

= 0.5 meters

Now add this 0.5 meters to 8 meters

Therefore we get ,

The measurement of the side of the square Hall = 0.5 + 8.0

= 8.5 meters.

Required to find :

1. Cost of fixing tiles

2. Area of the square

Solution :

Area of the square = side x side

Hence using this formula we are going to find the area of the hall.

Here is the calculations ;  

Area of the square Hall = 8.5 meters x 8.5 meters

= 72.25 meter^2

Ans : Area of the square is 72.25 meter^2

In the question, he also mentioned that

cost of fixing tiles for 1m^2 = Rs. 300

Cost of fixing tiles for 72.25 meter^2 = ?

=>. 72.25 x Rs. 300

=>. Rs. 21,675

Hence,

cost of fixing tiles for 72.25 meter^2 = Rs. 21,675.
