# The ratio between the length and breadth of a stadium is 5 : 3 and its perimeter is 256 metres. What will be the cost of leveling the ground of the stadium at the rate of Rs.2.50 per sq. metre.

 A) Rs.9600 B) Rs.8400 C) Rs.7200 D) Rs.6400

 A) Rs.9600

Let the length be 5x and the breadth be 3x.

Perimeter = $$\Large 2 \left(5x+3x\right)$$ = 16x

$$\Large 16x = 256$$

x = 16

Length of the stadium = 80 m.

Area of the ground = $$\Large 80 \times 48$$ = 3840 sq. m.

The cost of leveling the ground = Rs.2.50 / sq m .

Total cost of leveling the ground= $$\Large 3840 \times 2.50$$ = Rs.9600
