Question

tne area of a square is 42.25 m2 . find the side of the square. if the tiles measuring 13cm × 13cm are paved on the square area, find how many tiles are required for paving it ?

Answer 1

The area of a square is L x W but since the square has equal sides it is just S² or side².

 

So the side is the square root of 42.25m² which is 6.5m.

 

The second part of the questions once us to find how many tiles fits in area. 

 

I recommend converting cm to m by dividing 100.

 

So each tile is .13m x .13m. That means the area of 1 tile is .0169m². So if we have 42.25m2, all we do is divide.

42.25/.0169 is 2500, so I think there will be 2500 tiles
