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.
Zvimwe zvinobvunzwa zvakanyanya
Unogona here kumbobvira waziva kuti nzvimbo yetriangle inopfuura 1000 m2?
Area = ½ × base × height, using the perpendicular height. A triangle with base 6 and height 4 has area ½ × 6 × 4 = 12.
Chii chinonzi nzvimbo yechiedza?
Area = π × radius². A circle of radius 5 has area π × 25 ≈ 78.54.
Unogona here kumbobvira waziva kuti nzvimbo yechikwereti inopfuura here?
A rectangle 5 yakareba uye 4 yakakura ine nzvimbo 5 × 4 = 20.
Chii chinonzi nzvimbo yetrapezi?
Area = ½ × (base₁ + base₂) × height, kuongorora pakati pezviviri zvakaenzana mativi uye ku multiplies ne height pakati pavo.
Chii chinonzi nzvimbo yeparallelogram?
Area = base × height, using the perpendicular height, not the sloped side length.
Nei perimeter nguva dzose ichiratidza dashi?
Perimeter inopihwa kune rectangles uye circumference kune macircles. Triangles, trapezoids uye parallelograms vanoda kwavo kutsvuka kwenzvimbo, izvo hazvina kuiswa, saka perimeter yavo inodzokera pasina.
Ndezvipi zvinyorwa zvandinoda kuti ndipfuure?
Zvese zvinoitwa nechimiro chakasarudzwa chete. Chiso chinoda chete radius; mativi ekureba nekumukwegura haasi kutariswa.
API — kushandisa iyi kalkulator kubva code
Nhare iyi calculator semahara JSON endpoint - hapana chikuru zvinodiwa. Kutumira nzvimbo mavara pasi separameter query kana JSON. Chii zvachose chaunoisa kunze chinoshandisa default iyo peji iri rakasviba nayo; parameter isiri yechokwadi inonzi 400, uye haisi zero. Tora yakazara API docs →
