The approximate length of a side of the square field is 22 feet.
Given,
A square field has an area of 479 ft².
We need to find out what is the approximate length of a side of the field.
Give your answer to the nearest foot.
It is given as :
Area = side²
Find the length of a side of a square.
Side = length of a side
Area = side²
We have,
Area = 479 ft²
479 = side²
Side = √479
Side = 21.886
Rounding to the nearest foot.
Side = 21.886 feet
0.886 can be round to 1 foot.
So,
Side = 22 feet.
Thus the approximate length of a side of the square field is 22 feet.

~ y = -(1/20)x²
~ x = (1/20)y²
The equation of parabola will be y=(1/20)x² .
Given,
Focus : (0, 5)
Directrix : y = -5
Now,
The standard equation of parabola is : x² = 4ay or y² = 4ax .
Focus is above directrix, it opens up
x²=4ay
a is distance from directrix to vertex
Since it opens up, a is positive
from -5 to 0 is 5 units
x²=4(5)y
x²=20y
solve for y
divide both sides by 20
y=(1/20)x²
