Open Question: i want put fencing on my 1.24 acre of land with eight feet distance of stone pillor , how many pillors needed!?

assume that land is in square shape.
a^2 =1.24 acre
a^2 = 1.24x 4046.85 square meter
a^2 = 5018.094
a = v5018.094
a = 70.83 meter

so perimeter , 4a = 4×70.83 = 283.35 meter

we know 1 meter = 3.28 feet

so perimeter = 283.35×3.28 = 929.40 feet

since one pillar is 8 feet long,
total number of pillar required = 929.40/8 = 116.175

so approx 117 pillars are required.
