Question

1. The length and breadth of a rectangular field are in the ratio 9:5. If the area of the
field is 14580 square metre, find the cost of surrounding the field with a fence at
rate of 3.25 per metre.​

Answer 1

Answer:

The cost of surrounding will be 1053 rupees.

Answer 2

Step-by-step explanation:

length =9x

breadth=5x

area of a rectangle=l×b=14580m²

9x*5x=14580

45x²=14580

x²=324

X=18.

substitute value of X in length and breadth

length=9x

=9(18)

=162m

breadth=5x

=5(18)

=90m

perimeter of a rectangle=2(l+b)

=2(162)(90)

=29160m

cost for fencing per meter=3.25 rupees

=29,160×3.25

=94,770rupees

therefore cost of fencing an area with length 162m and breadth 90m is 94,770rupees
