Question

A square wall, is covered with square tiles. There are 85 tiles altogether along the two diagonals. How many tiles are there on the whole wall???

Answer 1

the tiles are of equal sizes.

Answer 2

There would be 85 tiles altogether if you summed up the diagonals and didn't count the center tile twice.

At any rate the sides must be 86/2 tiles wide and the area (number of tiles) will be \[A_{square}=s^2=(\frac{86}{2})^2\]

Answer 3

I had to think about it too :)

Answer 4

what does the 's' and 'A' STAND for?

Answer 5

A=area, s= side

Answer 6

thank u .... appreciate it :)

Answer 7

There are 43 tiles along a diagonal? Then surely the area is\[(\frac{1}{\sqrt{2}}s)^2\] As you, i probably didn't understand the question.

Answer 8

With s=43=diagonal

Answer 9

@henpen can u explain your formula?

Answer 10

And use
