Question

Mr.Jain buys 6100 small marble tiles to tile a large square hall in his house. He then finds that he needs to buy 141 more tiles such that he can cover the complete floor without any over lap. How many tiles are there along any one side of the hall?

Answer 1

Answer:

79

Step-by-step explanation:

No. of tiles Mr. Jain brought at first=6100

No. of tiles he brought later=141

So, total no. of tiles he brought=6100+141=6241

He brought 6241 tiles for a square hall to fill the area completely.

One side of a square=√area

Here we can assume that the total area is 6241

So, tiles there are along a side of the hall=

√6241=79

Hence, there are 79 tiles along any one side of the hall.

Hope this helps. Please mark this answer as the brainliest answer.

Answer 2

Answer:

79 tiles

Step-by-step explanation:

Let tiles along one side be x

when he bought 6100 tiles, he lacked 141 tiles

so, total tiles=6100+141=6241 tiles

since Mr. Jain wanted to tile a square hall,

so, in the hall, no. of rows=no. of columns

=>x²=6241

=>x=79 tiles
