Step-by-step explanation:
—Dimension1 =25 and dimension2 =4
Area=25*4=100
Perimeter=2(25+4)=2(29)=58.
—-Dimension1 =12.5 and dimension2 =8
Area=12.5*8=100
Perimeter=2(12.5 + 8)=2(20.5)=41

Answer:
So the correct option is First one
i.e 
Step-by-step explanation:
Given:
Area of Shaded part = 9 π square feet
To Find :
Area of Circle = ?
Solution:
90 degree center angle is equivalent to an area of 9 Π square feet
So, 360 degree center is equivalent to area A which is the area of the complete circle.
So the Ratio will be
Setting the given statements in proportion:

On solving we get the required

So the correct option is First one
i.e 
Alternate Method:
Shaded part is of 90°
Area of Shaded part = 9 π square feet
And Full Circle is of 360° that is 4 sector of 90°



So the correct option is First one
i.e 
On solving this we get
