Question

What is the cost of fencing a square shaped plot of land with side length 25 metres, if the rate of fencing is ₹ 9 per metre ?

• A. ₹ 1,000
• B. ₹ 9,000
• C. ₹ 1,900
• D. ₹ 900

Answer 1

The correct option is D ₹ 900

Fencing is always done on the boundary of the plot of land .

Given, length of the square plot of land = 25 m

Perimeter of the plot of land = 4 x Side
= 4 x 25 m
= 100 m

Given, cost of fencing 1 metre of land = ₹ 9

So, total cost of fencing = Cost of fencing per metre x Total length of boundary of the plot (perimeter of the plot )
$\therefore$ Cost of fencing 100 m
= 9 x 100
= ₹ 900
