5501 m^2

(1/tan b - tan a ) / (1/tan a - tan b)

((1-tan a tan b)/tan b) / ((1-tan b tan a)/ tan a)

1- tan a tan b gets cancelled when divided

tan a/ tan b= tan a cot b= rhs

k^2= (12*16)/ area of plot

area of plot = (12*16*250000*250000)/100*100*1000*1000 to convert it to km^2

which will give 1200 sq. km

2!Rh + 2!rh+ 2!(R^2 - r^2)=512!

2! (12*10+12x+ 10^2-x^2)=512!

120 + 12x + 100- x^2=256(by cancelling 2 and pi)

x^2 -12x +36 =0

(x-6)^2=0

x=6cm

how what r we supposed to do

could u pls send the whole sum with the solution properly solved. iit would help. thanks

it is 0.48 as 7- 41.123=3.877 and not 3.123

how do u know tht 3 people got 40 ?? @karthikrs

1 is not taken as an odd no. it iss a unique no.

how???
