Answer:

Step-by-step explanation:
We are given the following in the question:
Area of rectangle = 81 square meter.
Let l be the length of the rectangle and b be the breadth of rectangle.
Then, we can write,

Perimeter of rectangle =

Putting values, we get,

Answer = 196.34ML
If the length is 10cm and the diameter 5cm then the answer would be 196.34ML or 6.63 FL Oz
To build a fence is perimeter so 45.5 x 2= 91
155 - 91= 64
Since that is still two sides you divide 64 by 2 and get 32.
Then area is l x w so 32 x 45.5= 1456
