Mo tēnei tātaitai
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.
Ko nga pātai e pā ana
He pēhea te kimi i te rohe o te tapawhā?
Ko te rohe = ½ × pūtake × tiketike, mā te whakamahi i te tiketike pātata. He tapawhā me te pūtake 6 me te tiketike 4 te rohe ½ × 6 × 4 = 12.
He aha te rohe o te porowhita?
Ko te rohe = π × radius². He rohe te porohita o te radius 5 π × 25 ≈ 78.54.
He pēhea te kimi i te rohe o te tapawhā?
Whakarea te roanga e te whānui. He rohe te tapawhā 5 roa me te 4 whānui 5 × 4 = 20.
He aha te wāhi o te pororapa?
Ko te rohe = ½ × (take 1 + take 2) × tiketike, e whakawaenga ana i ngā taha whakarara e rua me te whakarea e te tiketike i waenganui i a rātou.
He aha te rohe o te tāpiri?
Ko te rohe = pūtake × tiketike, mā te whakamahi i te tiketike pātata, ehara i te roanga o te taha whakawhāiti.
He aha te take i ētahi wā e whakaatu ana te porohita i tētahi tāpa?
E hoatu ana te pereti mō ngā tapawhā me te whakawhitinga mō ngā porohita. E hiahiatia ana e ngā tapawhā, ngā pātū me ngā porohita te roa o tō rātou taha, kāore i tāurutia, nō reira ka waiho wātea to rātau pereti.
He aha nga āpure e hiahiatia ana e au hei whakapūtā?
Ko ērā anake e whakamahia ana e te hanga tīpako. E hiahiatia ana e te porohita te radius anake; Ka whakakāhoretia ngā āpure whānui me te tiketike mō ia.
API — whakamahi tēnei tātaitai mai i te waehere
E kī ana tēnei tātaitai hei wāhi mutunga kore JSON - kāore he kī e hiahiatia ana. Ka tukuna ngā uara āpure i raro nei hei tohutoro pātai, JSON rānei. Anything you omit uses the same default this page is pre-filled with; an unknown parameter is a 400, never a silent zero. Ka pānui te papatono API katoa →
