Atik sa a
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.
Kesyon ki poze souvan
Kijan pou w jwenn zòn yon triyang?
Avèk baz 6 ak wotè 4, yon triangle gen yon zòn ½ × 6 × 4 = 12.
Ki sa ki se zòn nan nan yon cercle?
Avèk yon cercle de rayon 5, zòn nan se π × 25 ≈ 78.54.
Kijan pou w jwenn zòn yon rektang?
Multipli longè pa lajè. Yon rektang ki 5 longè ak 4 lajè gen yon zòn 5 × 4 = 20.
Ki sa ki se zòn nan nan yon trapezoid?
Areal = ½ × (base₁ + base₂) × wotè, ki se mwayèn de de bò paralèl yo ak multiplié pa wotè ant yo.
Ki sa ki se zòn nan nan yon paralelogram?
Avèk yon ranje longè ki pi long, li ka itilize pou mezire longè, pa sèlman longè yon liy.
Poukisa perimèt la montre yon ti kras yon ti kras?
Perimèt la bay pou rektangulè yo epi circumférence pou cercles. Triangles, trapezoïdes ak parallelograms bezwen longè bò oblique yo, ki pa antre, se konsa perimèt yo se kite vid.
Ki jaden mwen dwe ranpli?
Se sèlman sa fòm ki chwazi a itilize. Yon cercle bezwen sèlman radius li; jaden lajè ak wotè yo pa pran an kont pou li.
API — itilize sa a calculateur soti nan kòd
Apèl sa a calculateur kòm yon gratis JSON pwent-de-fini - pa gen okenn kle ki nesesè. Envoye valè jaden anba a kòm paramèt kesyonè oswa JSON. Anything you omit uses the same default this page is pre-filled with; an unknown parameter is a 400, never a silent zero. Li dokiman API a an antye →
