Question

a garden is 40 m long and 25m wide. there is a path 1m wide inside the garden along its sides. if the path is to be paved with square marbel stones of 20m ×20m cm, find the number of stone to cover the path

Answer 1

area of garden=40×25
=1000m sq
area of path=1000-(40-2×25-2)
=1000-874
=126m sq.
area of one marble=20×20
=400cm sq.
no of marble=126×100×100/400
=126×25
=3150
Hence, 3150 marbles are required to pave the path.

Answer 2

The number of stone to cover the path is 3150

Step-by-step explanation:

Length of garden = 40 m

Breadth of garden = 25 m

There is a path 1m wide inside the garden along its sides.

Inner length = 40-(1+1)=38 m

Inner breadth = 25-(1+1)=23 m

Area of path = Outer area - Inner area

Area of path = $(40 \times 25)-(38 \times 23)$

Area of path =$126 m^2$

the path is to be paved with square marbel stones of 20m ×20m cm

Area of square stone = $0.2^2 = 0.04 cm^2$

The number of stone to cover the path =$\frac{126}{0.04}=3150$

Hence the number of stone to cover the path is 3150
