Given :

A road 2 m broad surrounds a square park 4225 m² in area.

Size of marble is 25 cm by 8 cm.

Price of each marble is Rs 50.

To Find :

Total cost.

Solution :

Side of square road is :

$A^2 = 4225\ m^2\\\\A = 65\ m$

Area of road = $4\times 65\times 2 \ m^2=520\ m^2$

Number of marbles required is :

$N = \dfrac{A}{a}\\\\N = \dfrac{520\times 10^4\ cm^2}{200\ cm^2}\\\\N = 26000$

It is given that price per marble is Rs 50.

So, total price required is :

$P = Rs \ 50\times 26000 \\\\P = Rs \ 13,00,000$

Hence, this is the required solution.
