⬛ Area Calculator

ଏହି ଗଣନାକାରୀ ବିଷୟରେ

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.
