Answer 2

The cost of making its boundary at rupees 2.25 per metre is Rs.211.5

Step-by-step explanation:

Cost of laying tiles in a rectangular ground at rupees 5 per square meter is rupees 2400

So, Area of ground =$\frac{2400}{5} =480 m^2$

Width of boundary = 15 m

Area of ground = $Length \times Breadth = Length \times 15$

So, $Length \times 15 = 480$

Length = $\frac{480}{15} = 32$

Perimeter of rectangular ground = 2(l+b)=2(32+15)=94 m

Cost of making boundary of 1 m = Rs.2.25

Cost of making boundary of 94 m = $94 \times 2.25= Rs.211.5$

Hence the cost of making its boundary at rupees 2.25 per metre is Rs.211.5
