# How Many Stone will be Required in the Rectangle Courtyard? If

The number of paving stones each measuring 2.5m x 2m required to pave a rectangular courtyard 30 m long and 17.5 m wide, are:

- 99
- 105
- 33
- 80

**Answer: (2) 105**

**Explanation:-**

Area covered by a paving stone = 2.5 x 2 = 5.0 m square

The total area of a rectangular courtyard = 30 x 17.5 = 525 m square

Number of paving stones in courtyard = 525/5 = 105 stones.

Hence, the answer is (2) 105
