Step-by-step explanation: The formula for finding the area (A) of a two-dimensional shape depends on the shape being considered. For example:
The area of a rectangle is calculated by multiplying its length and width: A = l x w
The area of a triangle is calculated by multiplying its base and height and dividing the result by 2: A = (b x h) / 2
The area of a circle is calculated by multiplying pi (π) by the square of its radius: A = πr^2
Radius to the power of 2, or r^2, is the radius of a circle multiplied by itself. In the context of finding the area of a circle, the radius squared is used because it represents the amount of space enclosed by the circle. The value of r^2 is multiplied by pi (π) to find the area of the circle.
