The term “area” in mathematics refers to the size or measure of a two-dimensional shape. It quantifies the amount of space inside a shape or figure.

To calculate the area of simple shapes, you often need to use specific formulas. Here are some commonly used formulas for finding the area of different shapes:

1. Rectangles and Squares:
To find the area of a rectangle, multiply its length (l) by its width (w): Area = l × w.

For squares, since all sides are equal, you can also use the formula: Area = side × side, where “side” refers to the length of one side of the square.

2. Triangles:
For triangles, the area can be determined using the formula: Area = (base × height) / 2. Here, the base represents the length of the bottom side of the triangle, and the height is the length from the base to the opposite vertex.

3. Circles:
To calculate the area of a circle, you need to know its radius (r). The formula for the area of a circle is: Area = π × r², where π (pi) is a constant approximately equal to 3.14159.

4. Parallelograms:
The area of a parallelogram is given by the formula: Area = base × height. Here, the base refers to the length of one of the parallel sides, and the height is the perpendicular distance between the base and the opposite side.

5. Trapezoids:
To find the area of a trapezoid, you can use the formula: Area = (sum of the bases) × height / 2. The height is the perpendicular distance between the bases, and the sum of the bases refers to the sum of the lengths of the parallel sides.

Remember to use the appropriate units (such as square units) when expressing the area, depending on the units used for the dimensions of the shape.

It is crucial to know and understand these basic formulas for finding area as they serve as building blocks for more complex shapes and calculations.
