Answer:
there is no particular case mentioned so we are free to use any real world problem.
Say the problem is :
How much fence would you need to replace the fence of a 30 foot by 40 foot playground?
Final answer:
140 feet.
Step-by-step explanation:
Given that size of the playground is 30 foot by 40 foot.
That means length L = 30 foot
Width W = 40 foot.
Now we need to find the length of the fence that is needed for the playground. Fencing is done on the sides of the playground so basically we are going to find the perimeter.
which can be found using formula
perimeter = 2(L+W)
perimeter = 2(30+40)
perimeter = 2(70)
perimeter = 140
Hence total fence needed is 140 feet.
