Question

a side of a square plot is 80 meters. how many square stones can be fixed in it . if the side of the stone is 1.6 meters.

Answer 1

the area of the square plot = 80×80 = 6400
the area of the stone = 1.6×1.6 = 2.56
squares stones can be fixed in it = 6400/2.56= 2500

The answer for your question is as followed,
_____________________________________________________________
>>Now,
     Area of the square plot = s²
                                            ⇒ 80×80
                                            ⇒ 6400m²
     Area of the stone = s²
                                  ⇒ 1.6×1.6
                                  ⇒ 2.56m²
  ∴ No. of stone = 6400m² ÷ 2.56m²
                            ⇒2560

Answer: We will need need 2500 stones.
