Menentukan Panjang Perimeter (untuk sesuatu keluasan kawasan)

Ramai orang tahu keluasan sesuatu kawasan tanah mereka, kadang - kadang ianya adalah dalam ekar mahupun hektar dan mahu tahu panjang pagar yang akan mereka bina kelak. Di sini saya telah mengekstrak formula seperti berikut :

See 1 acres of land has an area of approximately 4047m^2. Now the perimeter of that land depends upon the shape of the land i.e. it can be square, rectangular etc. With just area of land of 4047m^2 we can only find out the side of square field as area of square is = a^2 which can be equate to 4047 and then we can find the value of a by squaring root of 4047. i.e.

a^2= 4047

a= underoot of 4047

a= 63.61 approx

and as we know perimeter of square is 4a

Therefore it perimeter will = 4x63.61=254.45 m approx

Berikut adalah carta perimeter untuk keluasan kawasan tertentu yang mungkin anda ingin ketahui :-

(0.1 hectares) ¼ acre = 127 metres = 416.667 ft
(0.2 hectares) ½ acre = 180 metres = 590.551 ft
(0.3 hectares) ¾ acre = 220 metres = 721.785 ft
(0.41 hectares) 1 acre = 255 metres = 836.614 ft
(0.81 hectares) 2 acres = 360 metres = 1181.1 ft
(1.21 hectares) 3 acres = 441 metres = 1446.85 ft
(1.62 hectares) 4 acres = 509 metres = 1669.95 ft
(2.02 hectares) 5 acres = 569 metres = 1866.8 ft
(4.05 hectares) 10 acres = 805 metres = 2641.08 ft
(8.09 hectares) 20 acres = 1141 metres = 3743.438 ft
(16.19 hectares) 40 acres = 1609 metres = 5278.871 ft
(20.24 hectares) 50 acres = 1800 metres = 5905.512 ft

Semoga formula ini memberikan anda idea untuk membina pagar atau tembok anda kelak. Tuhan memberkati!
