Malunga nale Calculator
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 ebuza rhoqo
Ufumana njani indawo yobubanzi besithathu?
Indawo = ½ × isiseko × ubude, usebenzisa ubude obuthe nkqo. Ii triangles ezinesiseko 6 nobude 4 zineendawo ½ × 6 × 4 = 12.
Yintoni indawo yojikelezo?
Indawo = π × umda². Umda wesangqa ojikelezayo 5 unendawo π × 25 ≈ 78.54.
Ufumana njani indawo yobubanzi be-rectangle?
Ukuphindaphinda ubude ngobubanzi. Uxande olude 5 nobubanzi 4 lunomhlaba 5 × 4 = 20.
Yintoni indawo ye-trapezoid?
Indawo = ½ × (isiseko 1 + siseko 2) × ubude, ukuphakama kweendawo ezimbini ezihambelanayo kunye nokunyuka kobude phakathi kwazo.
Yintoni indawo yodibano?
Indawo = isiseko × ubude, usebenzisa ubude obuthe nkqo, hayi ubude becala elithe nkqo.
Kutheni i-perimeter ngamanye amaxesha ibonisa i-dash?
Umda unikezelwa kwii-rectangles kunye nojikelezo lwee-circles. Ii-triangles, i-trapezoids kunye ne-parallelograms zifuna ubude becala elithe tye, elingangeniswa, ngoko umda wabo ushiye ongenanto.
Ziziphi iindawo endifuna ukuzigcwalisa?
Kuzo kuphela ezo isimbo esikhethiweyo sisebenzisayo. Umda ufuna kuphela umda; ububanzi nobude bendawo akufuneki kuthathelwe ingqalelo.
