Malunga nale khadi
An area calculator finds how much surface a 2D shape covers. Pick the shape, enter its dimensions, and it returns the area — and, where the sides are known, the perimeter or circumference. Only the fields the chosen shape actually needs are used; the rest are ignored.
Each shape has its own formula: a rectangle is length × width, a triangle is ½ × base × height, a circle is π × radius², a trapezoid is ½ × (base₁ + base₂) × height, and a parallelogram is base × height. For a rectangle 5 long and 4 wide the area is 5 × 4 = 20 and the perimeter is 2 × (5 + 4) = 18; a triangle with base 6 and height 4 has area ½ × 6 × 4 = 12; a circle of radius 5 has area π × 25 ≈ 78.54. Perimeter is shown for rectangles and circles, but not for triangles, trapezoids or parallelograms, whose slanted sides are not entered.
Area calculations are needed for flooring, paint, fabric, land, and any project measured by surface. Make sure all dimensions use the same unit, and the area comes out in that unit squared.
Imibuzo ebuzwa kaningi
Ungathola kanjani indawo ye-triangle?
Indawo = ½ × isisekelo × ubude, usebenzisa ubude obuhamba phambili. I-triangle enesisekelo 6 nobude 4 inendawo ½ × 6 × 4 = 12.
Yini indawo yesiga-nyezi?
Indawo = π × umsila². Igobolondo lomsila 5 linendawo π × 25 ≈ 78.54.
Ungathola kanjani indawo ye-rectangle?
Ukuphindaphinda ubude ngebanzi. Ukwe-thela obungama-5 ubude no-4 ububanzi unendawo engu-5 × 4 = 20.
Yini indawo ye-trapezoid?
Indawo = ½ × (isizinda 1 + isizinda 2) × ubude, ukulinganisela amaphesenti amaphiko amabili alinganayo nokuphindaphinda ubude phakathi kwazo.
Yini indawo ye-parallelogram?
Indawo = isisekelo × ubude, usebenzisa ubude obuhamba phambili, hhayi ubude bengxenye ehamba phambili.
Kungani i-perimeter ngamanye amaxesha ibonisa i-dash?
I-perimeter inikezelwa kuma-rectangles ne-circumference kuma-circles. Ama-triangles, ama-trapezoids nama-parallelograms adinga ubude bengxenye ejikelezayo, okungukuthi, afakwanga, ngakho-ke i-perimeter yabo ishiya i-empty.
Yini imikhakha engidinga ukuyigcwalisa?
Kulezi kuphela ezisetshenziswa isimo esikhethiwe. Igobolondo lidinga kuphela umjikelezo; ububanzi nebanga lokuphakama zilahlekile.
API — sebenzisa le calculator kusuka kukhodi
Nquma le calculator njenge JSON evulekile yendawo yokuqeda - akukho isithonjana esidingekayo. Thumela amaxabiso endawo ngezansi njengezilungiselelo zombuzo noma i-JSON. Noma yini ongayishiya isebenzisa iphutha elifanayo elifakwe ngaphambili lekhasi; ipharamitha engaziwa yi-400, ayikho i-zero emnyama. Funda i-API egcwele →
