Step-by-step explanation:
Shawn's living room is a square, so all four sides are the same length. Area of a square is A = s², and we know the area is 196 ft². If substitute this for A:
196 ft² = s²
Take square root of both sides:
s = √(196 ft²)
s = ±14 ft
Since measurements of lengths can't be negative, s must be +14 ft. So Shawn's living room is 14 ft x 14 ft.
Answer:
Area - 201.062ft

ANSWER
EXPLANATION
We have that the shaded sector is subtended at 210 degrees at the center of the circle that has a radius of 12 inches.
The area of a sector is given as:
where A = angle the sector subtends at the circle's center
So, we have that:
That is the answer.
