The question doesn't give you any values at all so it would be impossible to determine what the exact area of the shaded region is.

Hope that helps.

lets calculate the area of the sector = angle/360 22/7 (1)^2

shaded area = area of square - (area of square - area of the sector BCA) - (area of the circle - area of the sector DCA)

= 1 - (1-90/360*TT*1) -(1-90/360*TT*1)

= 1-1-1+TT/4+TT/4

= TT/2 - 1

*TT = 22/7

How do you know the two arcs are quarter-circles?kuntalkkc wrote:quite easy...

half of the shaded region=area of quarter circle-half area of sq=Pi*1/4-1/2

total shaded region=2(pi/4-1/2)=pi/2-1=TT/2-1...ans option 4....any doubt?

I agree that if we had that information we could solve, but the question doesn't include that info and we certainly can't (and are never expected to) make any assumptions of that nature on the GMAT.
