An old manuscript reveals that a landowner in the time of king Arthur held 3.00 acres of plowed iand plus a live stock area of 25.0 perches by 4.00 perches. What was the total area in :
(a) The old unit of roods
(b) The more modern unit of square meters ?
Here 1 acre is a area of 40 perches by 4 perches, 1 rood is 40 perches by 1 perch and 1 perch is 16.5 feet.
Hi,
1 acre = 40 perches by 4 perhes
1 rood = 40 perches by 1 perch
1 perch = 16.5 feet
Now,
1 acre = 40 perches by 4 perches
=> 1 acre = 660 feet by 66 feet = 43560 feet2
=> 3 acres = 130680 feet2
25 perches by 4 perches = 412.5 feet by 66 feet = 27225 feet2
So, the total area in feet2 is (130680+27225) feet2 = 157905 feet2
1 rood = 40 perches by 1 perch
=> 1 rood = 660 feet by 16.5 feet = 10890 feet2
Since, 10890 feet2 = 1 rood
=> 157905 feet2 = 14.5 roods
Therefore,
(a) (a) Total area in the old units of roods is 14.5 roods
(b) (b) 1 feet2 = 0.0929 m2
Total area is 157905 feet2 which when converted to m2 becomes 14669.85 m2
