Write a real world problem involving multiple steps. then solve your problem.

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

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.
