A road 2 m broad surrounds a square park 4225 m² in area. Find the cost of
marbles each of 25 cm by 8 cm in size on the road at Rs 50 per piece of marble.​

Answers

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 :

[tex]A^2 = 4225\ m^2\\\\A = 65\ m[/tex]

Area of road = [tex]4\times 65\times 2 \ m^2=520\ m^2[/tex]

Number of marbles required is :

[tex]N = \dfrac{A}{a}\\\\N = \dfrac{520\times 10^4\ cm^2}{200\ cm^2}\\\\N = 26000[/tex]

It is given that price per marble is Rs 50.

So, total price required is :

[tex]P = Rs \ 50\times 26000 \\\\P = Rs \ 13,00,000[/tex]

Hence, this is the required solution.
