Answer:
113.04m^2
Step-by-step explanation:
Surface area for Base and top

Surface area for the other part

you will get
113.04m^2
The first choice is the correct answer. Note that for S(t) = 5t/(t+1):At t = 0, S = 0At t = 1, S = 5(1/2)At t = 2, S = 5(2/3)And as t increases, S approaches 5. (The pattern 1/2, 2/3, 3/4...gets closer and closer to 1).
Step-by-step explanation:
Let the size of their father's land be x.
The first born received x/4
The second, third and fourth born each received 1/6 * (x - x/4) = 3x/24 = x/8
The portion received by the last born = x - (x/4 + 3*x/8) = x - (x/4 + 3x/8) = x - (5x/8) = 3x/8
3x/8 = 3hectares
3x = 24
x = 8.
. : The initial size of the parcel land was 8 hectares.
