Jul 12, 2023 · Area is the measure of the space occupied by the boundary of the shape. It is the total space occupied by the given figure and it is measured in unit square. The number of the unit square covered inside the figure is referred to as the area of the figure. The standard unit of the area is unit2, i.e. m2, cm2, etc.
Area formula The area of a two dimensional shape or geometric figure is the space contained within its perimeter. The exact area of many common shapes can be calculated using well-defined formulas.

A rectangle is a quadrilateral with four right angles. It is one of the simplest shapes, and calculating its area only requires that its length and width are known (or can be measured). A quadrilateral by definition is a polygon that has four edges and vertices. In the case of a rectangle, the length typically refers to the longer two edges of the ...
There are many equations for calculating the area of a triangle based on what information is available. As mentioned in the calculator above, please use the Triangle Calculatorfor further details and equations for calculating the area of a triangle, as well as determining the sides of a triangle using whatever information is available. Briefly, the...
A trapezoid is a simple convex quadrilateral that has at least one pair of parallel sides. The property of being convex means that a trapezoid's angle does not exceed 180° (in contrast, a concave quadrilateral would), while being simple reflects that trapezoids are not self-intersecting, meaning two non-adjacent sides do not cross. In a trapezoid, ...
A circle is a simple closed shape formed by the set of all points in a plane that are a given distance from a given center point. This distance from the center to any point on the circle is called the radius. More detail can be found regarding circles on the Circle Calculator page, but to calculate the area, it is only necessary to know the radius,...
A sector of a circle is essentially a proportion of the circle that is enclosed by two radii and an arc. Given a radius and an angle, the area of a sector can be calculated by multiplying the area of the entire circle by a ratio of the known angle to 360° or 2π radians, as shown in the following equation: or The Farmer and his Daughter – Sectioning...
An ellipse is the generalized form of a circle, and is a curve in a plane where the sum of the distances from any point on the curve to each of its two focal points is constant, as shown in the figure below, where P is any point on the ellipse, and F1 and F2are the two foci. When F1 = F2, the resulting ellipse is a circle. The semi-major axis of an...
A parallelogram is a simple quadrilateral which has two pairs of parallel sides, where the opposite sides and angles of the quadrilateral have equal lengths and angles. Rectangles, rhombuses, and squares are all special cases of parallelograms. Remember that the classification of a "simple" shape means that the shape is not self-intersecting. A par...

Oct 3, 2024 · Area is a measure of a region’s size on a surface. In simple words, area helps us to know how much space is occupied by a closed surface in a plane. The area is defined only for closed shapes. For a 2D geometric entity, area depends upon the shape and dimensions of the entity. It is calculated in sq units of units2 (eg: cm2, m2).
