Our comprehensive area calculator helps you calculate the area of various geometric shapes. Choose a shape, enter the required dimensions, and get the area instantly with step-by-step explanations.
The area of a rectangle is calculated by multiplying its length by its width.
A square is a special type of rectangle where all sides are equal, so the area is the side length squared.
The area of a triangle is half the product of its base and height.
The area of a circle is π (approximately 3.14159) times the square of its radius.
The area of a trapezoid is the average of the two bases multiplied by the height.
The area of a parallelogram is the product of its base and height (the perpendicular distance between bases).
The area of an ellipse is π times the product of its semi-major and semi-minor axes.
The area of a circular sector is proportional to its angle, calculated as a fraction of the full circle's area.
If a room is 12 feet long and 10 feet wide:
You would need 120 square feet of flooring to cover the room.
If you have a circular garden with a radius of 8 feet:
The garden covers approximately 201 square feet.
A standard NBA basketball court is 94 feet long and 50 feet wide:
The court covers 4,700 square feet.
If a triangular plot of land has a base of 100 feet and height of 60 feet:
The plot covers 3,000 square feet.
