Web5 Apr 2024 · This is equal to about 166 sq yards. Now, suppose you have brought the property in Sector 30 of Gurugram, an area where the circle rate currently is Rs 5,000. After multiplying the area with the per sq yard circle rate, you arrive at the stamp duty you will have to pay. 166 x 5,000 = Rs 8.30 lakhs WebSo the area of the sector over the total area is equal to the degrees in the central angle over the total degrees in a circle. And then we just can solve for area of a sector by multiplying both sides by 81 pi. 81 pi, 81 pi-- so these cancel out. 350 divided by 360 is 35/36. And so our area, our sector area, is equal to-- let's see, in the ...
