Ịchọta gburugburu nke square: usoro na ọrụ

N'akwụkwọ a, anyị ga-atụle ka esi gbakọọ perimeta nke square ma nyochaa ihe atụ nke idozi nsogbu.

Usoro okirikiri

Site n'ogologo akụkụ

Perimeta (P) nke square nhata na nchikota ogologo nke akụkụ ya.

P = a + a + a + a

Ebe ọ bụ na akụkụ niile nke square hà nhata, enwere ike ịkọwa usoro a dị ka ngwaahịa:

P = 4 ⋅ a

N'akụkụ ogologo nke diagonal

Mpaghara (P) nke square hà nhata ngwaahịa nke ogologo diagonal ya na nọmba 2√2:

P = d ⋅ 2√2

Usoro a na-esote site na nha nke ogologo akụkụ (a) na diagonal (d) nke square:

d = a√2.

Ihe atụ nke ọrụ

Ọrụ 1

Chọta gburugburu nke square ma ọ bụrụ na akụkụ ya bụ 6 cm.

Mkpebi:

Anyị na-eji usoro nke uru akụkụ ahụ gụnyere:

P = 6 cm + 6 cm + 6 cm + 6 cm = 4 ⋅ 6 cm = 24 cm.

Ọrụ 2

Chọta gburugburu square nke diagonal ya bụ √2 -ahụ

1 Ngwọta:

N'iburu n'uche uru anyị maara, anyị na-eji usoro nke abụọ:

P = √2 cm ⋅ 2√2 = 4 sentimita.

2 Ngwọta:

Gosipụta ogologo akụkụ n'usoro nke diagonal:

a = d / √2 = √2 cm/√2 = 1 sentimita.

Ugbu a, na-eji usoro mbụ, anyị na-enweta:

P = 4 ⋅ 1 cm = 4 cm.
