Area is a measure of the size of a two-dimensional shape or the surface of a three-dimensional object. It is typically measured in square units, such as square meters or square inches.
There are several different formulas for calculating the area of various shapes. For example, the area of a rectangle is found by multiplying its length by its width, while the area of a circle is found using the formula pi x radius^2.
Here are five examples of different shapes and their corresponding formulas for calculating area:
- Rectangle: area = length x width
- Triangle: area = (base x height)/2
- Circle: area = pi x radius^2
- Trapezoid: area = (base1 + base2)/2 x height
- Ellipse: area = pi x semi-major axis x semi-minor axis
It is important to note that the units used for the measurements must be the same in order to accurately calculate the area. For example, if the length and width of a rectangle are both measured in feet, the area will be in square feet.
