# Family parcels

In father will he divided the land so that the older son had three bigger part than younger son. Later elder son gave 2.5 ha field to younger and they had both the same. Determine the area of family parcel.

Result

x =  10 ha

#### Solution:

x=a+b
a = 3b
a-2.5 = b + 2.5

a+b-x = 0
a-3b = 0
a-b = 5

a = 152 = 7.5
b = 52 = 2.5
x = 10
