The term "area" in the context of plane figures refers to the measure of the space enclosed within the boundaries of a two-dimensional shape. The formula to calculate the area depends on the specific shape of the figure. Here are the formulas for some common plane figures:
Rectangle:
Area (A) = Length × Width
Square:
Area (A) = Side × Side (since all sides of a square are equal)
Triangle:
Area (A) = (Base × Height) / 2
Circle:
Area (A) = π × (Radius)^2 or A = π × (Diameter/2)^2
Parallelogram:
Area (A) = Base × Height
Trapezoid:
Area (A) = (Sum of the lengths of the parallel sides) × Height / 2
These are just a few examples, and there are formulas for various other plane figures as well. The unit of measurement for area is typically square units (e.g., square inches, square centimeters, square meters). When working with irregular shapes, more advanced methods such as calculus or decomposition into simpler shapes may be used to calculate the area.
