Question

A 2m wide path is constructed around a square field having area 1156m² how many stones of size 12 cm × 8cm may be required to pave on the path

Answer 1

Answer:

Number of stone slabs = Area of path / area of a tile

= (12m*18m)/(24cm*15cm)

= (1200cm*1800cm)/(24cm*15cm)

= 50*120

= 6000

Answer 2

Answer:

Approximately 26667 or 26666 stones

Step-by-step explanation:  

Area = 1156 .sq m

so, side = root over 1156 = 34 m

so,  length of side of the square = 34 m (outside)

      length of side of the square = 30 m (inside)          

so,area of inner square =30×30 .sq m = 900 .sq m

so, area of the path = 256 .sq m

so, area of stones = 12×8 .sq cm = 96 .sq cm  or 0.0096 .sq m

so, the required number of stones = 256/0.0096 ≈ 26667 or 26666 stones
