Calculate the Area of Common Shapes
Our Geometry Area Calculator provides an easy way to find the area of common shapes like rectangles, circles, triangles, and more, complete with formulas and visual diagrams.
What is an Area Calculator?
An Area Calculator is a tool designed to compute the two-dimensional space enclosed by a shape. It's a fundamental utility for a wide range of applications, from students solving homework problems to homeowners planning a renovation or landscaping project. By providing the necessary dimensions for a given shape, the calculator applies the correct geometric formula to find the area, and can convert the result into various units of measurement.
How It Works: Geometric Formulas
The calculator uses standard, universally accepted formulas for each shape:
Rectangle: Area = Length × Width
Circle: Area = π × radius²
Triangle: Area = 0.5 × base × height
Simply select the tab for your desired shape, input the dimensions, and the calculator will show you the formula, the calculation, and the final result.
Frequently Asked Questions
How do you calculate the area of a room?
To calculate the area of a rectangular room, you multiply its length by its width. For example, a room that is 12 feet long and 10 feet wide has an area of 120 square feet (12 × 10). Our Area Calculator can find the area of various shapes.
What is the formula for the area of a circle?
The formula for the area of a circle is A = πr², where 'r' is the radius of the circle. You multiply Pi (approximately 3.14159) by the square of the radius.
How do you calculate the area of a triangle?
The area of a triangle is calculated by multiplying the base of the triangle by its height, and then dividing by two. The formula is: Area = 0.5 × base × height.
