a) Rs 500

b) Rs 510

c) Rs 530

d) Rs 540

correct answer is: b) Rs 510

**Explanation**

Here,

Length = 24 m

Breadth = 10 m

We know,

Perimeter of rectangle = 2 × (length + Breadth)

\therefore Perimeter of the field is =2\times\left(24+10\right) m

\rightarrow\left(2\times34\right) m

\rightarrow68 m

Now,

1 meter fencing cost = Rs 7.50

\therefore 68 meter fencing cost = Rs \left(7.50\times68\right)

\rightarrow Rs 510 **Ans: **The cost of fencing the field is Rs 510.
