Question

The area of a rectangular Park is 1560 m square and its breadth is 24 M find the length and perimeter of the park also find the cost of fencing it at rupees 22.50 per metre

Answer 1

$\textbf{ANSWER:}$

Given that:

•Area of the field =》 1560 sq. m

•Breadth =》 24 m

To find:

▪Length

▪Perimeter

▪Cost of fencing at Rs. 22.5 per m

Solution:

$Length = \frac{Area}{Breadth} \\ \\ = > \frac{1560}{24} \\ \\ = > 65 \: m$

$\\ Perimeter = 2(l + b) \\ = > 2(65 + 24) \\ = > 2 \times 89 \\ = > 178 \: m$



Cost of fencing = Perimeter × 22.5

=》Rs. 4005
_____________

⊙Length = 65 m

⊙Perimeter = 178 m

⊙Cost of fencing at Rs. 22.5 per m = Rs. 4005

Answer 2

area of rectangle=1560m²

So, l×b=1560

l = 1560/b

 = 1560/24

 = 65m

Now,

perimeter= 2(l+b)

               =2(65+24)

              =178m

cost of fencing=perimeter×22.5

= 178×22.5

= 4005 rupees
