How much fence woud you need to replace the fence of a 30 foot by 40 foot playgroumd how would you need to re sod the fence

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 lenght 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.
