The area of a circle is (pi) x (radius²) .
So 80 = (pi) (radius²)
Divide each side by pi : Radius² = (80/pi)
Take the square root
of each side: Radius = √ (80/pi)
= 5.0463 cm (rounded)
Considering that the hallway is rectangular in shape such that its perimeter is calculated by the equation,
P = 2L + 2W
where P is perimeter, L is length, and W is width. Substituting the known values,
10.4 = 2L + 2W
Dividing both sides of the equation by 2,
5.2 = L + W
W = 5.2 - L

Answer:
220 meter
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Area of square = 275 square meters
Side length (a) = 55 meters
We can calculate the perimeter of square by using following formula,
Perimeter of square = 4a
By putting the value, we get
Perimeter of square = 4 × 55 mt
= 220 meter
Hence, the perimeter of the square is 220 meter.
