The following are calculators to evaluate the area of five common shapes. The area of more complex shapes can usually be obtained by breaking them down into their aggregate simple shapes, and totaling their areas. This calculator is useful for calculating land area. Surface area is its analog on the two-dimensional surface of a three-dimensional object.
Area Of A Rectangle Calculator
Area of rectangle is the region covered by the rectangle in a two-dimensional plane. The opposite sides of the rectangle are equal and parallel to each other. To be noted, a parallelogram also has its opposite sides equal and parallel to each other but the angles are not equal to 90 degrees.
Area Of A Triangle Calculator
The area of a triangle is defined as the total region that is enclosed by the three sides of any particular triangle. Basically, it is equal to half of the base times height
Area Of A Circle Calculator
Area of a circle is the region occupied by the circle in a two-dimensional plane. It can be determined easily using a formula, A = πr2, where r is the radius of the circle. A detail circle calculator is available here
Area Of A Square Calculator
Area of a square is defined as the number of square units needed to fill a square. In general, the area is defined as the region occupied inside the boundary of a flat object.
Area Of Sphere Calculator
Area of sphere or total surface area of sphere is the region covered by a surface of a spherical object in a three-dimensional space. Since the sphere is a complete curved shape therefore the curved surface area is equal to the total area of sphere. It is also called lateral surface area.
