If the area is a square, then we can use this equation:
A = s²
For the area. We don't know the area, but we know the perimeter, which we can use this equation:
P = 4s
We know this perimeter so we can solve for s:
314 = 4s
s = 78.5
Now we can use the first equation to solve for the area:
A = s²
A = 78.5²
A = 6162.25
Rounded to 2SF:
6200 ft² (answer B)

Let x ft be the side-length of the playground.
- PhilipLv 61 month ago
Side length of square playground = (314/4) ft = 78.5 ft. Playground area = (78.5)^2
square feet = 6162.25 (ft)^2 = 6,200 (ft)^2 rounded to nearest 100. Correct option is

WOW! the hard way:
314 linear feet of fencing, Without a GATE for entry?
Square, so you say.
Four sides divided into the length. 314/4 = 78.5 each side.
Multiply the one side by itself for area.
78.5 * 78.5 = 6162.25
So I would presume we are now putting a gate into the fence, which would lead to B) 6,200 as the answer. (That be One Huge Gate, man).

s = 314/4 = 78.5 ft
A = 78.5^2 = 6162.25 sq ft
