Given :-
To Find :-
- The expression that is equivalent to one of the choices given .
Solution :-
As we know that ,
→ (-) × (-) = (+)
→ (-) × (+) = (-)
→ (+) × (-) = (-)
→ (+) × (+) = (+)
On using these open the brackets ,
→ -1/3 - 1( -4 + 1/6 )
→ -1/3 - 1(-4) + -1(+1/6)
→ -1/3 (-)(-)(1* 4) (+)(-) (1*1/6)
On using now above stated rules ,
→ -1/3 +4 -1/6
Somewhat rearrange ,
→ 4 -1/3 -1/6
Take (-) as common,
→ 4 - (1/3 +1/6)
<u>Hence Option </u><u>(</u><u>d)</u><u> </u><u>&</u><u> </u><u>(f) </u><u>are</u><u> correct .</u>
I hope this helps.

Step-by-step explanation:
Let's organise our information :
- the radius of the circle is r=14 cm
- we can get the area of the shaded by substracting the area of that triangle from that quarter
The area of the cercle's quarter area is :
The area of the triangle is :
NOw the area of the shaded segment :
The scale factor is 2 or 200%
