Applied Math - Geometry - Flashcard 2 - "Area"

The area of a parallelogram is given by the formula: Area = base × height.

The area of a circle is calculated using the formula: Area = π × r², where r is the radius.

The area of a rectangle is calculated using the formula: Area = length × width.

The area of a triangle is given by the formula: Area = (base × height) / 2.

The area of a trapezoid is calculated using the formula: Area = (1/2) × (base1 + base2) × height.

Rounding is important in area calculations to provide a practical and usable answer, especially in real-world applications.

To convert feet and inches to square feet, first convert the entire measurement to feet (e.g., 12 ft 4 in = 12 + 4/12 = 12.33 ft), then calculate the area.

The area of a shaded region is found by subtracting the area of the unshaded part from the total area of the figure.

Area is measured in square units (e.g., cm², in², ft²), which represent the two-dimensional space occupied by a shape.

To find the area of a composite figure, break it down into simpler shapes, calculate the area of each, and then sum them up.
