Kutsvaga perimeter ye square: formula uye mabasa

Muchinyorwa chino, tichaona nzira yekuverenga iyo perimeter ye square uye kuongorora mienzaniso yekugadzirisa matambudziko.

Perimeter Fomula

Nekureba kwedivi

Perimeter (P) yeskweya inoenzana nehuwandu hwehurefu hwemativi ayo.

P = a + a + a + a

Sezvo mativi ese echikwere akaenzana, iyo formula inogona kuratidzwa sechigadzirwa:

P = 4 ⋅ a

Pamwe kureba kweiyo diagonal

Perimeter (P) yeskweya yakaenzana nechigadzirwa chehurefu hwediagonal uye nhamba 2√2:

P = ⋅ 2√2

Iyi fomula inotevera kubva pachiyero chehurefu hwedivi (a) uye diagonal (d) yechikwere:

d = a√2.

Mienzaniso yemabasa

Basa 1

Tsvaga perimeter ye square kana rutivi rwayo rwuri 6 cm.

Sarudzo:

Isu tinoshandisa fomula umo kukosha kwedivi kunobatanidzwa:

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

Basa 2

Tsvaga perimeter yeskweya ine diagonal iri √2 ona

1 Mhinduro:

Tichifunga nezve kukosha kunozivikanwa kwatiri, isu tinoshandisa yechipiri fomula:

P = √2 masendimita ⋅ 2√2 = 4cm.

2 Mhinduro:

Ratidza kureba kwedivi maererano nediagonal:

a = d / √2 = √2 cm/√2 = 1cm.

Zvino, tichishandisa fomula yekutanga, tinowana:

P = 4 ⋅ 1 masendimita = 4 masendimita.
